c8eb2dccc5 CCR patch: Reorganise the oxygen partial pressure calculations
This patch responds to the side effects that the CCR code has had with
respect to ceilings in OC dives and dive plans. Dive ceilings are now
calculated correctly again.

The following were performed:
1) remove the oxygen sensor and setpoint fields from the gas_pressures
   structure.
2) Re-insert setpoint and oxygen sensor fields in the plot_data structure.
3) Remove the algorithm that reads the o2 sensor data and calculates the
   pressures.po2 value from function fill_pressures() in dive.c and save
   it as a separate function calc_ccr_po2() in profile.c.
4) Activate calc_ccr_po2 from function fill_pressures() in profile.c.
5) Move the relative position of the call to fill_pressures() within the
   function create_polt_info_new() in profile.c.

bc9df4652f CCR patch: Calculate the correct partial gas pressures for CCR dives
This patch adds code to the function fillpressures() in dive.c to
allow calculating o2 pressures, based on the data from the po2
sensors in the system. The following changes were made:
1) add code to perform po2 calculations for CCR with 1, 2 or 3
   oxygen sesnors.
2) Add four fields to the gas_pressures structure in dive.h. This
   allows communication of data between the function that calls
   get_pressures() and the return of partail pressure values to the
   calling function.
3) Delete the fields for setpoint and gas partial pressures from
   the structure plot_info. All partial pressures (from instruments
   as well as calculated) now reside in the pressures structure
   that forms part of plot_info.
4) Perform changes in several parts of profile.c to make use of the
   pressures structure in plot_info.

613402f6c9 Correctly copy all information in an event
Instead of trying to use add_event() to reinsert events we simply copy the
memory and adjust the pointers.

Using add_event() lost the gas mix and gas index information on gaschange
events - and this prevent switches between cylinders with the same gasmix
to be rendered correctly.

49c9ad199f CCR patch: Oxygen partial pressures
This patch does three things:
1) A new function fill_o2_values() is added to profile.c. This
   fills all oxygen sesnsor and setpoint values that have been
   zeroed before in order to save space in the dive log. This
   recreates the full set of sensor values obtained from the
   original CCR xml log file.
2) Function fill_o2_values() is activated in function create_
   plot_info_new() in profile.c
3) The calling parameters to function fill_pressures() in dive.c
   are changed. The last parameter is now a pointer to a structure
   of divecomputer. This will be needed in the last patch of the
   present series of three patches.

46bb02e8fc CCR patch: Import and store oxygen sensor data
This patch allows the importing of oxygen sensor and setpoint data from
Poseidon CCR dive logs.
1) Change parse-xml.c to read up to three oxygen sensor values from xml.
   and to store the information in sample structures
2) Change parse-xml.c to read o2 setpoint values fro xml and to store
   it in sample structures
3) Change dive.c to delete all sensor and setpoint values where
   subsequent samples have sensor/setpoint values that are the same.
4) Change profile.c to store the sensor/setpoint values from the samples
   into plotinfo.
5) Change the sample Poseidon xml log in the dives directory to ensure
   the correct order and hierarchy of the dive and divecomputer nodes.

5b14ed16ac Add "download into private trip" dialog checkmark
This adds a checkbox for the divecomputer download dialog that allows you
to tell the download to put the newly downloaded dives into a trip of
their own. That in turn will disable the dive merging with any existing
dives, which means that you will not mix up your newly downloaded dives
with any old dives.

That, in turn, is very convenient of you know that some of the dives were
done by other divers (or from testing that happened during servicing etc),
or the dive dates etc were wrong because the dive computer date had reset
due to battery changes etc.

Once you have all the dives in a private trip of their own, you can then
fix them up (delete dives you don't want to merge etc), and then after all
the data is ok you might want to merge the cleaned-up results with
previous trips etc, and then manually ask subsurface to merge the dives or
whatever.

ecf0408aae Make SAC values in planner settings respect unit settings
So far, the fields for the two SAC rates did not show a unit and were implictly l/min.
Now they respect the settings for volume units. This was harder than I thought for two reasons:

1) Imperial units for SAC are cuft/min but a typical value would be .70. So I made the point
the field prefix and what is entered is actually hundreth of cuft per minute.

2) I had to get the rounding right in order not to get effects like 20l/min become .70 cuft/min (19800 ml/min
internally) which would then become 19l/min when switching back.

While being at it, I gave the gradient factors '%'-signs as units.

3aaf8b1f5a Make gas use statistics be coherent and more complete
The gas use logic in the dive statistics page is confused.

The SAC case had a special case for "unknown", but only for
the first gas. Other gases had the normal empty case.

Also, the logic was really odd - if you had gases that weren't used (or
pressures not known) intermixed with gases you *did* have pressure for,
the statistics got really confused.

The list of gases showed all gases that we know about during the dive,
but then the gas use and SAC-rate lists wouldn't necessarily match,
because the loops that computed those stopped after the first gas that
didn't have any pressure change.

To make things worse, the first cylinder was special-cased again, so it
all lined up for the single-cylinder case.

This makes all the cylinders act the same way, leaving unknown gas use
(and thus SAC) just empty for that gas.

It also fixes the SAC calculation case where we don't have real samples,
and the profile is a fake profile - possibly with gas changes in between
the fake points. We now make the SAC calculations match what we show -
which is admittedly not at all necessarily what the dive was, but at
least we're consistent.

4583cd8e09 Picture handling: cleaning up the mess
We had pointers to data structures on the stack which we frequently
reallocated. These data structure contain basically a filename and an
offset. We then create a hash of the pointers to those datastructures with
the filename being the key. And then we passed those pointers around
through a Qt model(!!!) only in order to then later look up by filename
what the offset might be.

I am at a loss for words for the lunacy behind this design.

How about we just remember the offsets and pass the integers around?

825eb019ab Planner: show mean depth
Almost invisible, mostly looking like an odd bug in the profile code,
there was a tiny red line at depth 0 in the planned profile. Turns out
that was the missing mean depth. We didn't populate enough data in the
dive computer of the dive we generated from the plan (and the length of
the depth line was incorrectly determined by the duration of the dive
instead of the duration stored in the dive computer).

74616cdddf Rename event: correctly replace event with new one
I don't like that the event structure includes the variable length array.
That really makes it a pain to change the name of an event (on the flip
side, freeing events is easier I guess).

Anyway, to correctly rename an event we need to actually remove the event
from the correct dc and then add a new event with the new name. The
previous code was insane (it only worked if the new name was of smaller or
equal length, otherwise it had a beautiful buffer overflow).

And of course we need to do this both for the current_dive and the
displayed_dive.

c539c8f861 Remove the .used member of the cylinder structure
Instead calculate this information on the fly, taking into account all
dive computers on the dive in questions.

There is one wrinkle to this - previously we abused the '.used' member to
make sure that a manually added cylinder didn't disappear the moment it
was added (think of the workflow: you add a cylinder, then you add a gas
change to that cylinder -> right after you add it it is unused and would
not be shown).

I am thinking that we might have to add the "manually_added" property to
the properties that we store in XML / git.

7821b87983 Use the last 'diveid' when merging dives for one dive computer
When we merge two dives into the same dive because a divecomputer had
incorrectly considered it two separate dives (due to surface time within
the dive) we should pick the dive ID from the later dive to be the
diveid of the resulting merged dive.  Otherwise we might re-download the
(now merged) partial dive.

This is a rather unusual special case, but it actually hit me with the
Uemis on my last dive in Palau: Chandelier Cave has multiple surface
points where you can spend time admiring the cave above water, and the
Uemis (but not my Suunto's) decided that the dive was actually four
short dives back-to-back.

This fixes a bug when due to a faulty download the same dive from two dive

eb47b2a8d8 Get rid of crazy empty tag_list element at the start
So this is totally unrelated to the git repository format, except for
the fact that I noticed it while writing the git saving code.

The subsurface divetag list handling is being stupid, and has a
initial dummy entry at the head of the list for no good reason.

I say "no good reason", because there *is* a reason for it: it allows
code to avoid the special case of empty list and adding entries to
before the first entry etc etc.  But that reason is a really *bad*
reason, because it's valid only because people don't understand basic
list manipulation and pointers to pointers.

So get rid of the dummy element, and do things right instead - by
passing a *pointer* to the list, instead of the list. And then when
traversing the list and looking for a place to insert things, don't go
to the next entry - just update the "pointer to pointer" to point to
the address of the next entry. Each entry in a C linked list is no
different than the list itself, so you can use the pointer to the
pointer to the next entry as a pointer to the list.

This is a pet peeve of mine. The real beauty of pointers can never be
understood unless you understand the indirection they allow. People
who grew up with Pascal and were corrupted by that mindset are
mentally stunted. Niklaus Wirth has a lot to answer for!

But never fear. You too can overcome that mental limitation, it just
needs some brain exercise. Reading this patch may help. In particular,
contemplate the new "taglist_add_divetag()".

689fe36030 Initial implementation of git save format
This saves the dive data into a git object repository instead of a
single XML file.

We create a git object tree with each dive as a separate file,
hierarchically by trip and date.

NOTE 1: This largely duplicates the XML saving code, because trying to
share it seemed just too painful: the logic is very similar, but the
details of the actual strings end up differing sufficiently that there
are tons of trivial differences.

The git save format is line-based with minimal quoting, while XML quotes
everything with either "<..\>" or using single quotes around attributes.

NOTE 2: You currently need a dummy "file" to save to, which points to
the real save location: the git repository and branch to be used.  We
should make this a config thing, but for testing, do something like
this:

	echo git /home/torvalds/scuba:linus > git-test

to create that git information file, and when you use "Save To" and
specify "git-test" as the file to save to, subsurface will use the new
git save logic to save to the branch "linus" in the repository found at
"/home/torvalds/scuba".

NOTE 3: The git save format uses just the git object directory, it does
*not* check out the result in any git working tree or index.  So after
you do a save, you can do

     git log -p linus

to see what actually happened in that branch, but it will not affect any
actual checked-out state in the repository.

rint() is "round to nearest integer", and does a better job than +0.5
(followed by the implicit truncation inherent in integer casting).  We
already used 'rint()' for values that could be negative (where +0.5 is
actively wrong), let's just make it consistent.

Of course, as is usual for the messy C math functions, it depends on the
current rounding mode.  But the default round-to-nearest is what we want
and use, and the functions that explicitly always round to nearest
aren't standard enough to worry about.

9fca37acec Properly handle user dive merge requests
When the user asks to merge dives in the divelist, we would always use
the "try tp find matching dive computers and merge at an offset" model.

That is incorrect if the intent is to actually merge two *identical*
dives (with different dive computers), as opposed to merging two short
dives into one longer one with a surface interval.

Normally this doesn't ever trigger (the "same dive" merging will have
been done automatically after downloading from the dive computer), but
if the dive computer times are off, and the user fixes them, and then
asks to merge dives, we should use the non-offset dive merging logic.

We already have that "likely_same_dive()" function that is used to
determine when downloaded dives get merged, so just use it for the user
merge case too.

assemble all that into per tank statistics.

Strangely the value calculated here seems slightly higher than one would
expect from the overall SAC rate. This inconsistency should be
investigated a bit further, but my guess it it's based on the assumption
that the DC provided mean depth is possibly more accurate than what we can
calculate from the profile.
