8dbe3528b4 Limit to 4 the number of cylinders shown in the data frame
For dives with more than 4 cylinders, the frame got very crowded and we
needed a magnifier to see the numbers.
If we used more than four tanks, let's put the info in another frame, if not, print
the OTUs, the maxcns and the weight sytem in the new frame.
There is still room for two more short data.

Changed naming of nitrox and trimix mixes.

Changed cylinder description.

There are issues with the size of some translations.

a58d470bad Remove autogroup from the preferences and store per file instead
Having two spots to toggle autogroup had always been a clear sign of
insanity. The inconsistent ludicrous semantic of when we remembered the
state of autogroup was even worse.

This finally gets rid of that disaster and drops the autogroup setting
from the preferences and makes it instead a per file property. When you
save a file, it saves the state of the autogroup toggle. This seems much
more useful - you may have files where you want to create trips by
default. And others, where you don't.

d720e133d8 First step in cleaning up cylinder pressure sensor logic
This clarifies/changes the meaning of our "cylinderindex" entry in our
samples. It has been rather confused, because different dive computers
have done things differently, and the naming really hasn't helped.

There are two totally different - and independent - cylinder "indexes":

 - the pressure sensor index, which indicates which cylinder the sensor
   data is from.

 - the "active cylinder" index, which indicates which cylinder we actually
   breathe from.

These two values really are totally independent, and have nothing
what-so-ever to do with each other. The sensor index may well be fixed:
many dive computers only support a single pressure sensor (whether
wireless or wired), and the sensor index is thus always zero.

Other dive computers may support multiple pressure sensors, and the gas
switch event may - or may not - indicate that the sensor changed too. A
dive computer might give the sensor data for *all* cylinders it can read,
regardless of which one is the one we're actively breathing. In fact, some
dive computers might give sensor data for not just *your* cylinder, but
your buddies.

This patch renames "cylinderindex" in the samples as "sensor", making it
quite clear that it's about which sensor index the pressure data in the
sample is about.

The way we figure out which is the currently active gas is with an
explicit has change event. If a computer (like the Uemis Zurich) joins the
two concepts together, then a sensor change should also create a gas
switch event. This patch also changes the Uemis importer to do that.

Finally, it should be noted that the plot info works totally separately
from the sample data, and is about what we actually *display*, not about
the sample pressures etc. In the plot info, the "cylinderindex" does in
fact mean the currently active cylinder, and while it is initially set to
match the sensor information from the samples, we then walk the gas change
events and fix it up - and if the active cylinder differs from the sensor
cylinder, we clear the sensor data.

[Dirk Hohndel:  this conflicted with some of my recent changes - I think
		I merged things correctly...]

96db56f89c Allow overlapping (and disjoint) dive trips
We used to have the rule that a dive trip has to have all dives in it in
sequential order, even though our XML file really is much more flexible,
and allows arbitrary nesting of dives within a dive trip.

Put another way, the old model had fairly inflexible rules:

 - the dive array is sorted by time

 - a dive trip is always a contiguous slice of this sorted array

which makes perfect sense when you think of the dive and trip list as a
physical activity by one person, but leads to various very subtle issues
in the general case when there are no guarantees that the user then uses
subsurface that way.

In particular, if you load the XML files of two divers that have
overlapping dive trips, the end result is incredibly messy, and does not
conform to the above model at all.

There's two ways to enforce such conformance:

 - disallow that kind of behavior entirely.

   This is actually hard.  Our XML files aren't date-based, they are
   based on XML nesting rules, and even a single XML file can have
   nesting that violates the date ordering.  With multiple XML files,
   it's trivial to do in practice, and while we could just fail at
   loading, the failure would have to be a hard failure that leaves the
   user no way to use the data at all.

 - try to "fix it up" by sorting, splitting, and combining dive trips
   automatically.

   Dirk had a patch to do this, but it really does destroy the actual
   dive data: if you load both mine and Dirk's dive trips, you ended up
   with a result that followed the above two technical rules, but that
   didn't actually make any *sense*.

So this patch doesn't try to enforce the rules, and instead just changes
them to be more generic:

 - the dive array is still sorted by dive time

 - a dive trip is just an arbitrary collection of dives.

The relaxed rules means that mixing dives and dive trips for two people
is trivial, and we can easily handle any XML file.  The dive trip is
defined by the XML nesting level, and is totally independent of any
date-based sorting.

It does require a few things:

 - when we save our dive data, we have to do it hierarchically by dive
   trip, not just by walking the dive array linearly.

 - similarly, when we create the dive tree model, we can't just blindly
   walk the array of dives one by one, we have to look up the correct
   trip (parent)

 - when we try to merge two dives that are adjacent (by date sorting),
   we can't do it if they are in different trips.

but apart from that, nothing else really changes.

NOTE! Despite the new relaxed model, creating totally disjoing dive
trips is not all that easy (nor is there any *reason* for it to be
easty).  Our GUI interfaces still are "add dive to trip above" etc, and
the automatic adding of dives to dive trips is obviously still based on
date.

So this does not really change the expected normal usage, the relaxed
data structure rules just mean that we don't need to worry about the odd
cases as much, because we can just let them be.

e3ab1c0701 Update deco handling
This commit makes deco handling in Subsurface more compatible with the way
libdivecomputer creates the data. Previously we assumed that having a
stopdepth or stoptime and no ndl meant that we were in deco. But
libdivecomputer supports many dive computers that provide the deco state
of the diver but with no information about the next stop or the time
needed there. In order to be able to model this in Subsurface this adds an
in_deco flag to the samples. This is only stored to the XML file when it
changes so it doesn't add much overhead but will allow us to display some
deco information on dive computers like the Atomic Aquatics Cobalt or many
of the Suuntos (among others).

The commit also removes the old event based deco code that was commented
out already. And fixes the code so that the deco / ndl information is
stored for the very last sample as well.

8d2abc05f6 Remove nickname from divecomputer data structure
Having it there with the model information seemed to make sense but on
second thought it's the wrong spot to keep that information, especially
since we were storing it in the XML file in every single dive.

This change removes the nickname member from the divecomputer and makes
the rest of the code reasonably self consistent. It does not add much of

computer that we haven't seen before, we give them the option to set a

dcb6574dc4 Improve deco handling and add NDL support
This commit changes the code that was recently introduced to deal with
deco ceilings. Instead of handling these through events we now store the
ceiling (which in reality is the deepest deco stop with all known dive
computers) and the stop time at that ceiling in the samples.

This also adds support for NDL (non stop dive limit) which both dive
computers that appear to give us ceiling / deco information appear to
give us as well (when the diver isn't in deco).

If the mouse hovers over the profile we now add support for displaying the
NDL, the current deco obligation and (if we are able to tell from the
data) whether we are at a safety stop.

4c4dff7683 Convert Uemis downloader to directly create dives
The initial downloader reused the XML parsing of SDA files that was
implemented early in order to support the information extracted from the
SDA with the java applet. But creating this intermediary XML file and
handing it off to the XML import function always seemed like an ugly way
to do things. This became even more obvious when adding more features to
the Uemis downloader.

This commit completely changes the downloader to instead create dives and
record them directly.

This also adds support for divespots (which are stored in a seperate
database that needs to be queried after the divelog and dive entries have
been combined - the Uemis firmware clearly was written by monkeys on
crack - oh wait: I'm trusting these same people to get the deco right?).

This commit leaves the SDA import capability in the XML parser intact.
I'll remove that later. Because of this it actually adds a few lines of
code, but the overall change will be a substantial code deletion.

3f197336aa Remove 'tripflag' from dive trips
Both dives and dive trips have the same 'tripflag' thing, but they are
used very differently.  In particular, for dive trips, the only case
that has any meaning is the TF_AUTOGEN case, so instead of having that
trip flag, replace it with a bitfield that says whether the trip was
auto-generated or not.

And make the one-bit bitfields explicitly unsigned.  Signed bitfields
are almost always a mistake, and can be confusing.

Also remove a few now stale macros that are no longer needed now that we
don't do the GList thing for dive list handling, and our autogen logic

It simplifies the code a lot too, because it's much more natural to

ba3e6bcc51 Associate each dive trip with the dives in that trip
We already kept a count of dives per trip in order to figure out when
there are no more dives left and the trip needs to be freed.  Now we
explicitly keep track of the list of dives associated with the trip too,
which simplifies the "find the time of the trip" logic.

We may want to sort it in time, but for now this is mainly about trying
to keep track of the divetrip relationships explicitly.  I want to move
away from the whole "use the gtk tree model to keep track of things"
approach.

1ca1fe7994 Improve on divecomputer data handling
This simplifies the vendor/product fields into just a single "model"
string for the dive computer, since we can't really validly ever use it
any other way anyway.

Also, add 'deviceid' and 'diveid' fields: they are just 32-bit hex
values that are unique for that particular dive computer model.  For
libdivecomputer, they are basically the first word of the SHA1 of the
data that libdivecomputer gives us.

(Trying to expose it in some other way is insane - different dive
computers use different models for the ID, so don't try to do some kind
of serial number or something like that)

For the Uemis Zurich, which doesn't use the libdivecomputer import, we
currently only set the model name.  The computer does have some kind of
device ID string, and we could/should just do the same "SHA1 over the
ID" to give it a unique ID, but the pseudo-xml parsing confuses me, so
I'll let Dirk fix that up.

10ce60e212 Fix "prefer download" behavior

that is to be merged with an existing dive would have the same time stamp.
But as Linus pointed out even back then, this does fail if a dive has been

download from computer a, then download same dive from b, then improve
something in the parsing from computer a and try to redownload; the time
stamp could have changed).

fe4f13f184 Add special download modes to force updates from the divecomputer
This will hopefully not be something we need often, but if we improve
support for a divecomputer (either in libdivecomputer or in our native
Uemis code or even in the way we handle (and potentially discard) events),
then it is extremely useful to be able to say "re-download things
from the divecomputer and for things that were not edited in Subsurface,
don't try to merge the data (which gives BAD results if for example you
fixed a bug in the depth calculation in libdivecomputer) but instead
simply take the samples, the events and some of the other unedited data
straight from the download".

This commit implements just that - a "force download" checkbox in the
download dialog that makes us reimport all dives from the dive computer,
even the ones we already have, and an "always prefer downloaded dive"
checkbox that then tells Subsurface not to merge but simply to take the
data from the downloaded dive - without overwriting the things we have
already edited in Subsurface (like location, buddy, equipment, etc).

This, as a precaution, refuses to merge dives that don't have identical
start times. So if you have edited the date / time of a dive or if you
have previously merged your dive with a different dive computer (and
therefore modified samples and events) you are out of luck.

8514ec8723 Support merging of two adjacent dives
This introduces the notion of merging two disjoint dives: you can select
two dives from the dive list, and if the selection is exactly two dives,
and they are adjacent (and share the same dive trip), we support the
notion of merging the dives into one dive.

The most common reason for this is an extended surface event, which made
the dive computer decide that the dive was ended, but maybe you were
just waiting for a buddy or a student at the surface, and you want to
stitch together two dives into one.

There are still details to be sorted out: my Suunto dive computers don't
actually do surface samples at the beginning or end of the dive, so when
you stitch two dives together, the profile ends up being this odd "a
couple of feet under water between the two parts of the dive" thing.

But that's an independent thing from the actual merging logic, and I'll
work on that separately.

38c79d149d Simplify and clean up dive trip management
This adds a couple of helper functions to manage dive trips
("add_dive_to_trip()" and "remove_dive_from_trip()") and makes those
functions do the trip statistics maintenance (trip beginning times,
number of dives, etc).

This was needed because the dive merge cases for multiple dive
computers showed some rather nasty special cases: especially if the
new dive information has been loaded into an XML file with trips
auto-generated, merging several of these kinds of xml files with
multiple dives in several overlapping trips would completely confuse
our previous code.

In particular, auto-generated trips that had the exact same date as
previous trips (because they were generated from the same dive
computer) really confused the code that used the trip timestamp to
manage the trips.

Adding the helper functions allows us to get the general case right
without having to have each piece of code that handles trip
information having to bother about all the odd rules. It will
eventually also allow us to make the dive trip data structures more
logical: right now the dive trip list is largely designed around the
odd gtk model handling, rather than some more higher-level conceptual
relationship with the actual dives.

But for now, this keeps all the data structures unchanged, and just
modifies them using the new helper functions.

3d8c1e50fc Fix default filename handling errors
The default filename handling is broken in two different ways:

 (a) if we start subsurface with a non-existing file, we warn about
the inability to read that file, and then we exit without setting the
default filename.

This is broken because it means that if the user (perhaps by mistake,
by pressing ^S) now saves the file, he will overwrite the default
filename, even though that was *not* the file we read, and *not* the
file that subsurface was started with.

So just set the default filename even for a failed file open.

The exact same logic is true of a failed parse of an XML file that we
successfully opened. We do *not* want to leave the old default
filename in place just because the XML parsing failed, and possibly
then overwriting some file that was never involved with that failure
in the first place. So just get rid of all the logic to push the
filename saving into the XML parsing layer, it has zero relevance at
that point.

 (b) if we do replace the default filename with a NULL file, we need
to set that even if we cannot do a strdup() on the NULL.

This fixes both errors.

7f515eb7e5 Fix dive trip merging logic
We used to have very spotty logic for picking the dive trip when
merging two dives. It turns out that that spotty logic almost never
really matters, because in practice you'll never hit the situation of
merging two dives with different dive trips, but it *can* happen.

In particular, it happens when you use multiple dive computers, and
end up loading the dives from one computer on top of the dives of your
other computer. If the clocks of the dive computers was set
sufficiently close to each other, the dive merging logic will kick in
and you may now have slightly different times for the dives that get
merged, and the trip merging logic got *really* confused.

The trip management also depends on the trip dates being updated
correctly when the dives associated with a trip are updated (whether
added or removed), and the trip merging code did none of that.

This fixes it all up. Hopefully correctly.

01f1ccff14 Add support for visibility tracking and allow manual entry air temp
Turns out we had a data field for visibility as a length unit - but never
used it. I can never guess how much visibility we actually had on a dive -
but I think most everyone can assign a rating between abysmal (zero stars,
"I couldn't read my dive computer even right in front of my mask" - trust
me, I had some of those dives) to amazing ("five stars, I could see farther
than I though possible" - and I had one or two of those, too). So I
changed this to an integer and am re-using the star infrastructure we have
for the overall dive rating.

When displaying this I was dismayed that we are running out of space in
the "Dive Notes" notbook. So I moved this to the "Dive Info" notebook.
This is not consistent and not logical. I think we need to revisit the
notebooks and think about what we want to display where.

While adding the infrastructure to manually enter the visibility I went
ahead and added the ability to manually enter the air temperature as well
(that was one of the things missing in the previous commit).

94c98865a7 Improve on the DivingLog importer a bit
This adds a few fields that we parse, but more importantly it also tries
to dynamically decide if the sample temperatures and pressures are in
imperial or metric units.

Dirk suspects that DivingLog generally always does everything in metric,
and the reason why he has crazy sample data in imperial units (both for
pressure and temperature) may be due to a bug in the early Uemis
importer for DivingLog.

Which would actually make a lot more sense than DivingLog really being
so insane on purpose.

Anyway, Dirk's brother Jurgen seems to have everything in metric units,
which would be much saner.  Maybe we should throw away the support for
insane DivingLog files entirely, since it is possible that the only use
ever of the possible source of that bug was Dirk's use of the Uemis
importer.

But for now, we end up just guessing. Current guesses:

 - water temperature is below 32 dgC, so 32+ degrees is in Fahrenheit.

 - tank pressures are below 400 bar, so higher values than that must be
   psi.

HOWEVER, the reverse is also true: you may want to change the gasmix of

c4c636fb4f Fix missing save of (almost empty) cylinder information
If we have no explicit cylinder info at all (it's normal air, no size or
working pressure information, and no beginning/end pressure information),
we don't save the cylinders in question because that would be redundant.

Such non-saved cylinders may still show up in the equipment list because
there may be implicit mention of them elsewhere, notably due to sample
data, so not saving them is the right thing to do - there is nothing to
save.

However, we missed one case: if there were other cylinders that *did* have
explicit information in it following such an uninteresting cylinder, we do
need to save the cylinder information for the useless case - if only in
order to be able to save the non-useless information for subsequent
cylinders.

This patch does that. Now, if you had an air-filled cylinder with no
information as your first cylinder, and a 51% nitrox as your second one,
it will save that information as

  <cylinder />
  <cylinder o2='51.0%' />

rather than dropping the cylinder information entirely.

This bug has been there for a long time, and was hidden by the fact that
normally you'd fill in cylinder descriptions etc after importing new
dives. It also used to be that we saved the cylinder beginning/end
pressure even if that was generated from the sample data, so if you
imported from a air-integrated computer and had samples for that cylinder,
we used to save it even though it was technically redundant.

We stopped saving redundant air sample information in commit 0089dd8819
("Don't save cylinder start/end pressures unless set by hand").

c804c4e02e Partial rewrite of the dive trip code
This introduces a new data structure for dive trips - reuseing the struct
dive just got way too messy.

The dive_trip_t datastructure now allows the code to remember if the trip
was auto generated or if its time stamp changed when dives where added to
the trip during auto generation.

The algorithm also distinguishes between dives that were intentionally
added to a trip (either in an XML file or by adding them to trip in the
UI) and dives that were added to trips via autogen. Saving dives that were
added to trips via autogen makes that assignment "intentional".

With this partial rewrite several of the oddities of the old code should
be resolved - especially turning autogen on and off again should get the
divelist back to the previous stage.

Also, when dives are merged during file open or import we now try to pick
the correct tripflag (instead of just ignoring the tripflag completely and
resetting it to TF_NONE by mistake).

Finally, the dive trip debugging code got more verbose and is trying
harder to detect issues at the earliest time possible.

Calling edit from the context menu creates a combined editing widget that
contains both dive info and equipment. When editing cylinders or
weightsystems from that widget and confirming those edits with OK those
changes were already committed to the current_dive - regardless on which
dive the user clicked. Worse, even when the user clicked Cancel in the

This had especially confusing consequences when editing multiple dives.

As a workaround this commit adds a global edit_dive variable. This fake
dive is edited by the secondary editing widgets and if the user accepts
changes with OK then they are copied over to the current dive (or all
selected dives in multi dive editing mode).

b49b081bb9 Handle new dives correctly if trips exist
There is an interesting issue when adding new dives into a dive list with
existing trips. Since fill_dive_list walks the list backwards and trips
are determined by the timestamp of the first dive in a trip, it is
non-trivial to know when a dive is added if it should be part of an
existing trip or not. Let's say when we see the dive we can also see a
trip entry that starts four days earlier. Without looking forward in the
list of dives we cannot tell if this is a multi-day trip that this dive
would fit into, or if there is a break of more than tree days (our current
trip threshold).

Instead this commit adds a second scan of the dives in chronological order
that does the right thing for new dives.

c3debc10fd Allow modification and edits of trips
Now that we can load and store trips we needed to add the capability to
manipulate those trips as well.

This commit allows us remove a dive from a trip via a right click
operation on the dive list.

The commit also adds code to split a trip into two, to merge two trips and
to create a new trip out of a top level dive.

To make all that useful this commit changes the right-click on the dive
list to identify and act on the record we are actually on (instead of
acting on the selection).

The right-click menu ("context menu") changes depending which divelist
entry the mouse pointer is on - so different operations are offered,
depending on where you are.

We also add simplistic editing of location and notes for a trip (but the
notes are never displayed so far).

To make our lives easier this commit adds a link from the dive to the dive
trip it is part of. This allowed to hugely simplify the auto trip
generation algorithm (among other things). The downside of this change is
that there are now three different ways in which we express the
relationship of dives and trips: in the dive_trip_list, in the tree_model,
and with these pointers.  Somehow this screams that I should rethink my
data structures...

e315abf645 First cut of explicit trip tracking
This code establishes the explicit trip data structures and loads and
saves them in the XML data. No attempts are made to edit / modify the
trips, yet.

Loading XML files without trip data creates the trips based on timing as
before. Saving out the same, unmodified data will create 'trip' entries in
the XML file with a 'number' that reflects the number of dives in that
trip. The trip tag also stores the beginning time of the first dive in the
trip and the location of the trip (which we display in the summary entries
in the UI).

The logic allows for dives that aren't part of a dive trip. All other
dives simply belong to the "previous" dive trip - i.e. the dive trip with
the latest start time that is earlier or equal to the start time of this
dive.

This logic significantly simplifies the tracking of trips compared to
other approaches that I have tried.

The automatic grouping into trips now is an option that defaults to off
(as it makes changes to the XML file - and people who don't want this
feature shouldn't have trips added to their XML files that they then need
to manually remove).

For now you have to select this option, then exit the program and start it
again. Still to do is to trigger the trip generation at run time.

We also need a way to mark dives as not part of trips and to allow options
to combine trips, split trips, edit trip location data, etc.

The code has only had some limited testing when opening multiple files.

The code is known to fail if a location name contains unquoted special
characters like an "'".

This commit also fixes a visual inconsistency in the preferences dialog
where the font selector button didn't have a frame around it that told you
what this option was about.

21fd73515f Ignore Nitrox/He seetings when editing cylinders for multiple dives
When figuring out which cylinders to change in a multi-dive edit, we
already ignored the beginning and end pressures. But it turns out to make
more sense to also ignore the Nitrox / Helium settings.

Imagine you do a number of dives - for some reason your dive computer
records the wrong cylinder size in the downloaded logfile (like my uemis
does all the time). Dives will likely have different Nitrox percentage,
but you should still be able to simply fix the cylinder size for all dives
at once.

666538ec77 Add helper 'for_each_dive()' dive iterator
It's an easy thing to do, but the for-loop ends up being pretty ugly, so
hide it behind the macro.

It would be even prettier with one of the (few) useful C99 features:
local for-loop variables.  However, gcc needs special command line
options, and other compilers may not do it at all. So instead of doing

   #define for_each_dive(_x) \
      for (int _i = 0; ((_x) = get_dive(_i)) != NULL; _i++)

we require that the user declare the index iterator too, and the use
syntax becomes

   for_each_dive(idx, dive) {
	... use idx/dive here ...
   }

And hey, maybe somebody actually will want to use the index, so maybe
that's not all bad.

972669d636 Rework dive selection logic
This completely changes how we keep track of selected dives: instead of
having an array listing the selection ("selectiontracker") or trusting
the gtk selection information, just save the information about whether a
dive is selected in the dive itself.

That makes it trivial to keep track of the state of selection across
group collapse/expand events, or when changing the tree view model.  It
also ends up simplifying the code and logic in other ways.

HOWEVER, it does currently (re-)introduce an annoying oddity with gtk:
if you collapse a dive trip that has individual selections, gtk will
forget those selections ("out of sight, out of mind"), and when you do
*new* selections, the old hidden ones remain.

So there's some games required to make gtk do sane things.  We may need
to either explicitly drop selections when collapsing trips, or make sure
the group entry gets selected when collapsing a group that has
selections in it. Or something.

There may be other issues introduced by this too.

621761233b Redo dive editing
This commit addresses two issues:

We now can add / edit / delete equipment from the edit dive dialog

We now can edit multiple dives at once

The latter feature has some interesting design constraints:
It picks the 'selected_dive' as the one to start the edit from - so if
this dive already has some information filled in, that information needs
to be overwritten before it is stored in all of the dives. Similarly, only
changes to the cylinders or weightsystems are recorded. Also, the notes
field is not editable in the multi dive edit mode (as that didn't seem
useful).

The workflow seems to work best if using the multi-edit right after
importing new dives from a dive computer. The user then can select all the
new dives and only needs to edit things like location, divemaster, buddy,
weights, etc. once.

This commit will create some obvious conflicts with the commit that adds
exposure protection tracking. It was implemented on top of the tree_view
changes as it reuses some of the infrastructure for tracking the selected
dives.

Import (or adding a file on the command line after --import) means that

those get correctly renumbered. And importing marks the dive_list as

d6c2236b8a Automatically renumber new dives when they are "obvious".
When importing (or reading xml from files) new dives, we now renumber
them based on preexisting dive data, *if* such re-numbering is obvious.

NOTE! In order to be "obvious", there can be no overlap between old and
new dives: all the new dives have to come at the end.  That's what
happens with a normal libdivecomputer import, since we cut the import
short when we find a preexisting dive.

But if any of the new dives overlap the old dives in any way, or already
have been numbered separately, the automatic renumbering is not done,
and you need to do a manual renumber.

c15f798a85 Remove the ability to 'Import' .SDA files
We can instead 'Open' these files as they are just bastardized XML files.

This gets us back to a more consistent point where 'Import' gets data
directly from the dive computer (and hopefully soon we will add the
ability to load a dive directly from a uemis SDA to libdivecomputer),
and 'Open' loads a file from the filesystem of the computer we are
running on (this last sentence phrased so awkwardly as the uemis Zurich
SDA is a computer and presents a file system when connected via USB - it
just doesn't have the dive data in an accessible format in that file
system).

As a bonus we get to throw away quite a bit of code (the uemis specific
file handling, mini-XML parser with helper functions, the file open dialog
in the importer). Yay!

a93641b722 Calculate OTUs for every dive
The calculation assumes that the cylinderindex in each sample tells us
which PO2 the dive was breathing at that time. This needs to be verified
with dives where there is an actual gas switch.

No idea where to display them, yet. Far fewer people will care about this
than care about SAC - does this still rate a spot in the dive_list?
I guess I could make it part of the dive_info - but it's not editable.
It doesn't seem to fit with the equipment page (even though this is the
one editable field that is related - nitrox %)

682135838f Separate out the UI from the program logic
The following are UI toolkit specific:
gtk-gui.c   - overall layout, main window of the UI
divelist.c  - list of dives subsurface maintains
equipment.c - equipment / tank information for each dive
info.c      - detailed dive info
print.c     - printing

The rest is independent of the UI:
main.c i    - program frame
dive.c i    - creates and maintaines the internal dive list structure
libdivecomputer.c
uemis.c
parse-xml.c
save-xml.c  - interface with dive computers and the XML files
profile.c   - creates the data for the profile and draws it using cairo

This commit should contain NO functional changes, just moving code around
and a couple of minor abstractions.

89fe2c723f Show tank / nitrox / air consumption information in the info_frame
Even though we go down to an 8pt font the info_frame changes size when the
air info is added. I don't like this but want to see how Linus would like
this resolved before going overboard.

Minor tweaks to the formating (we don't need two decimals when printing
the liters of air consumed).

This patch does NOT remove the plot of the air information in the profile
graph. I think we want to remove that once we like the text where it is,
but I wanted to do one thing at a time.

0c4e1697db Be more careful about unit changes
When we change units, we need to flush any currently active dive
information in the old units, and then carefully reload it in the new
units.

Otherwise crazy stuff happens - like having current cylinder working
pressure values that are in PSI because that *used* to be the output
unit, but then interpreting those values as BAR, because we changed the
units.

Also, since we now properly import working pressure from Diving Log,
stop importing the (useless) cylinder description.  The Diving Log
cylinder descriptions are things like "Alu" or "Steel".  We're better
off just making up our own.

Finally, since Diving Log has cylinder size in metric, make sure that we
do the "match standard cylinder sizes" *after* we've done all the
cylinder size conversions to proper units.

Doing per-dive cylinder start/end pressures is insane, when we can have

dive, it needs to be per cylinder.

This makes the save format cleaner too, we have all the cylinder data in
