This patch concludes the calculation of gas pressure readings for CCR
dives. Duplicate diluent gas pressures are removed from the dive structure
and set to zero, as is done for the other gases.

This patch introduces a new structure holding partial pressures (doubles in bar) for
all three gases and a helper function to compute them from gasmix (which holds fractions)
and ambient pressure. Currentlty this works for OC and CCR, to be extended later to PSCR.
Currently the dive_comp_type argument is unused.

The old implementation was... let's call it creative.
This tries to actually get things right instead of using magic.

This commit doesn't do anything, yet. It just puts in place helper
infrastructure that will later allow us to cut and paste parts of the data
of one dive into another dive (or set of dives).

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.

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.

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.

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?

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).

The copy_dive assumed that the event being removed was from
current_dive, wich was until a very recent past. now it
can't assume that anymore, so instead of setting ev =
assumed_dive->event->next, we do a ev = current_dive->event->next.

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.

This used to work because we actually displayed the current_dive. Now with
displayed_dive the pointers are of course different! So we need to compare
the actual events instead.

Signed vs unsigned comparisons are such a pain. Since we want offsets to
be +/- 30 minutes around the dive we need to allow negative offsets - but

We carefully copied the dive computers and their samples and events, but
only for the second and later DCs. For the first DC we simply copied the
pointers but not what they were pointing at. So when the copied dive was
freed, those pointers in the original went to freed memory.
Not good.

This is kind of the inverse to copy_dive(). Instead of duplicating all the
data that the dive points to, it moves it to a new struct dive and zeroes
out the old one so there are no two sets of pointers to these data.

There is massive confusion about what we display when and where and which
dive structure (or pointer to a dive structure) contains which information
at which stage. This is the first step towards restructuring all of this.
This creates a global variable displayed_dive which at any point in time
should be what is displayed on screen (both in the profile and in the
maintab). It removes the editedDive concept from MainTab.

If the picture has a timestamp that was within 30 minutes of the start and
finish of the dive, we take it. Otherwise we don't.
If the timestamps of the images are off, the time shift dialog allows the
user to fix this.
And with this patch the user can select all the dives of a trip and all
the pictures they took on the trip and the "right thing" will happen.

It makes no sense to store a 64bit time stamp with every picture. Even the
32bit offset (in seconds) from the dive start is WAY overkill. But
switching to that makes the code much more simple in a number of spots.
And makes what is saved to the XML file easier to read, too.

The picture list is a single linked list where the pictures have a node to
their next element. When adding the same picture to two dives, things got
way way wrong and crashes were appearing.
This will replicate the information (filename, latitude and longitude) for
each dive that has the picture, BUT it still tries to save as much as
possible on the actual pixmap.

into smaller bits. A bit of code refactor was done in order to correct the
placement of a few methods.
ShiftTimesDialog::EpochFromExiv got moved to Exif::epoch dive_add_picture
is now used instead of add_event picture_load_exif_data got implemented
using the old listview code. dive_set_geodata_from_picture got
implemented using the old listview code.

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.

We should never pass permille values around as integers. And we shouldn't
have to decode the stupid value in more than one place.
This doesn't tackle all the places where we access O2 and He "too early"
and should instead keep passing around a gaxmix. But it's a first step.

When planning a dive, the dive could use more gas than is in the cylinder.
So getting a negative end pressure is a useful indication to the user that
there plan might not be a good one.
