This makes the dive trip auto-generation a separate pass from the
showing of the dive trips, which makes things much more understandable.
It simplifies the code a lot too, because it's much more natural to
generate the automatic trip data by walking the dives from oldest to
newest (while the tree model wants to walk the other way).
It gets rid of the most annoying part of using the gtk tree model for
dive trip management, but some still remains.

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

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.

The dive computer information right now contains (apart from the sample

- the vendor and product name of the dive computer
- the date of the dive according to the dive computer (so if you change

When this was first implemented the assumption was that a downloaded dive
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
merged with a download from a different dive computer before (think:
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).
This commit also fixes a silly omission in the merge_dives() function
(which ended up ALWAYS prefering the downloaded dive) and finally

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.

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.

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.

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.

We now throw away redundant events, just as we throw away other redundant

they are less than 61 seconds apart and identical.
This also improves the display of the remaining events in the profile as
we now show the value of the event, if it is present (for example for a
deco event we show the duration of the deepest stop).
Finally, for events that define a range (so they set the beginning flag
and assume and end flag some time later) we no loger show the triangle but
assume that some other code handles visualizing them (as happens for the

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.

Turns out we had a data field for visibility as a length unit - but never

"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

When displaying this I was dismayed that we are running out of space in

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

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

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

This had especially confusing consequences when editing multiple dives.
As a workaround this commit adds a global edit_dive variable. This fake
