Move the cylinder also to first position if first planner datapoint

When changing the date/time of a dive in the planner the dive may end
up in a totaly new position in respect to date/time of other dives in
dive list table. It can be moved to the past or the future before or after
other existing dives. It also could overlap with an existing dive.
This change enables identification of a new "virtual" dive list position
and based on this starts looking for previous dives.
Then it (as before the change) does init the deco calculation with any
applicable previous dive and surface interval.
If some of these applicable dives overlap it returns a neg. surface time
which is then used in the planner notes to prohibit display of results.

In the planner it is best practise to start the dive with the first
gas in the gaslist. Otherwise one would get a gaschange event at the
very beginning of a dive.
This change implements the following feature:
Automatically move a gas to position 0 in the gaslist if the user selects
this gas for the first dive data point.

In the planner if one adds two or more cylinders with the same gasmix
(e.g. back gas and bottom stage 18/45) the drop down and data in the
used gas column of the planner points table will be filled with a more
verbose string mentioning also the cyl number and the cyl type
description.
Makes it easier in such a case to select the right cylinder.
Introduces also a helper function which tells you if there is another
cylinder with the same gasmix as the provided cylinder.
This also has an option if it should consider unused cylinders or not.

Be even more restrictive regarding which cylinders can be removed from
the cylinder table in the planner.
Only if a cyliner is not used in the planned part of the dive
it can be removed.
It doesn't matter if there is another cylinder with same gasmix.

The `static int defaultWidth[]` definition in divelistview.cpp
could potentially end up missing an element which can later result
in out-of-bounds access when iterating through the list of
columns and updating their widths.
Add a couple of methods in DiveTripModel for setting and getting
the widths and use those. The default values are now pre-set in a
QVector in the DiveTripModel() constructor.
Throw warnings if out-of-bounds columns are requested.

This is really unrelated to my recent "multiple gas pressures" work, but
the test case from Gaetan Bisson showed that the logic for which
cylinders to show in the equipment tab was less than optimal.
We basically used to show only cylinders that were actively used, unless
you had the "display_unused_tanks" preference option set. That comes
from some dive computers reporting a *lot* of cylinders that the diver
really doesn't even have with him on the dive. And showing those extra
dummy cylinders gets pretty annoying after a time, which is why we
default to not showing unused tanks.
However, in Gaetan's case, he had a total of four cylinders on the dive:
the O2 and diluent bottle for the rebreather dive, and then bailout
bottles (both air and deco). And while the bailout bottles weren't
actually used, Gaetan had actually filled in all the pressure details
etc for them, and so you'd really expect them to show up. These were
*not* just some extraneous default cylinder filled in by an over-eager
dive computer.
But because the bailout wasn't used, the manual pressures at the end
were the same as at the beginning, and the "unused cylinder" logic
triggered anyway.
So tweak the logic a bit, and say that you show cylinder equipment not
only if it has been used on the dive, but also if it has any pressure
information for it.
So the o nly cylinders we don't show are the ones that really have no
interesting information at all, except for possibly the cylinder tank
type itself (which is exactly what the over-eager dive computer case
might fill in, usually in the form of a default cylinder type).

The idea of this flag is to be able to only to emit the

(fromClick == true).
MapWidgetHelper::selectedLocationChanged() listens for this signal
and only then it will select nearby dives based on a "small-cicle".
If "fromClick" is false, it's the backend or the dive list that
updated the selection and MapWidgetHelper::selectedLocationChanged()
should no be called.

Inside the QML Map class there is a MapItemView item.
This item uses a delegate that receive a "model" property from
the MapLocationModel, but infact that's a QObject with the MapLocation
defined properties. That's how MapItemView works.
The problem here is that "model" QObject cannot be cast back
to a MapLocation as the meta data in there does not include
a MapLocation sub-class, for some reason.
Even if using propery() on that QObject to fetch data like coordinates
works, instead of storing this strange object pointer, store the
MapLocation UUID (from dive_site) which is a uint32_t.
setSelectedUuid() deals with this oddity and finds the correct
MapLocation pointer in the table and dispatches a selectedLocationChanged()
signal for it.

Instead of maintaining a seperate latitude/longitude values
in C++ and passing them to QML separatelly, pass them as a QGeoCoordinate.

- add() will be used to add a MapLocation to the model with

this model so calling being<..>Rows() seems to be the "correct Qt

The QML Map widget requires a QAbstractListModel based model to operate
with good performance. Technically gpslistmodel.cpp can be used for that
same purpose (e.g. has GPS coordinates), but the way it updates
may complicate the Map widget integration.
Thus, a new model is created - MapLocationModel, with items of type
MapLocation, for an attempt for a clean project structure on the C++ side.
For now it only handles latitude and longitude.

This finally handles multiple cylinder pressures, both overlapping and
consecutive, and it seems to work on the nasty cases I've thrown at it.
Want to just track five different cylinders all at once, without any
pesky gas switch events? Sure, you can do that. It will show five
different gas pressures for your five cylinders, and they will go down
as you breathe down the cylinders.
I obviously don't have any real data for that case, but I do have a test
file with five actual cylinders that all have samples over the whole
course of the dive. The end result looks messy as hell, but what did
you expect?
HOWEVER.
The only way to do this sanely was
- actually make the "struct plot_info" have all the cylinder pressures
(so no "sensor index and pressure" - every cylinder has a pressure for
every plot info entry)
This obviously makes the plot_info much bigger. We used to have
MAX_CYLINDERS be a fairly generous 8, which seems sane. The planning
code made that 8 be 20. That seems questionable. But whatever.
The good news is that the plot-info should hopefully get freed, and
only be allocated one dive at a time, so the fact that it is big and
nasty shouldn't be a scaling issue, though.
- the "populate_pressure_information()" function had to be rewritten
quite a bit. The good news is that it's actually simpler now, although
I would not go so far as to really call it simple. It's still
complicated and suble, but now it explicitly just does one cylinder at
a time.
It *used* to have this insanely complicated "keep track of the pressure
ranges for every cylinder at once". I just couldn't stand that model
and keep my sanity, so it now just tracks one cylinder at a time, and
doesn't have an array of live data, instead the caller will just call
it for each cylinder.
- get rid of some of our hackier stuff, like the code that populates the
plot_info data code with the currently selected cylinder number, and
clears out any other pressures. That obviously does *not* work when you
may not have a single primary cylinder any more.
Now, the above sounds like all good things. Yeah, it mostly is.
BUT.
There's a few big downsides from the above:
- there's no sane way to do this as a series of small changes.
The change to make the plot_info take an array of cylinder pressures
rather than the sensor+pressure model really isn't amenable to "fix up
one use at a time". When you switch over to the new data structure
model, you have to switch over to the new way of populating the
pressure ranges. The two just go hand in hand.
- Some of our code *depended* on the "sensor+pressure" model. I fixed all
the ones I could sanely fix. There was one particular case that I just
couldn't sanely fix, and I didn't care enough about it to do something
insane.
So the only _known_ breakage is the "TankItem" profile widget. That's
the bar at the bottom of the profile that shows which cylinder is in
use right now. You'd think that would be trivial to fix up, and yes it
would be - I could just use the regular model of
firstcyl = explicit_first_cylinder(dive, dc)
.. then iterate over the gas change events to see the others ..
but the problem with the "TankItem" widget is that it does its own
model, and it has thrown away the dive and the dive computer
information. It just doesn't even know. It only knows what cylinders
there are, and the plot_info. And it just used to look at the sensor
number in the plot_info, and be done with that. That number no longer
exists.
- I have tested it, and I think the code is better, but hey, it's a
fairly large patch to some of the more complex code in our code base.
That "interpolate missing pressure fields" code really isn't pretty. It
may be prettier, but..
Anyway, without further ado, here's the patch. No sign-off yet, because I
do think people should look and comment. But I think the patch is fine,
and I'll fix anythign that anybody can find, *except* for that TankItem
thing that I will refuse to touch. That class is ugly. It needs to have
access to the actual dive.
Note how it actually does remove more lines than it adds, and that's
despite added comments etc. The code really is simpler, but there may be
cases in there that need more work.
Known missing pieces that don't currently take advantage of concurrent
cylinder pressure data:
- the momentary SAC rate coloring for dives will need more work
- dive merging (but we expect to generally normally not merge dive
computers, which is the main source of sensor data)
- actually taking advantage of different sensor data from different
dive computers
But most of all: Testing. Lots and lots of testing to find all the
corner cases.

This is a very timid start at making us actually use multiple sensors
without the magical special case for just CCR oxygen tracking.
It mainly does:
- turn the "sample->sensor" index into an array of two indexes, to
match the pressures themselves.
- get rid of dive->{oxygen_cylinder_index,diluent_cylinder_index},
since a CCR dive should now simply set the sample->sensor[] indices
correctly instead.
- in a couple of places, start actually looping over the sensors rather
than special-case the O2 case (although often the small "loops" are
just unrolled, since it's just two cases.
but in many cases we still end up only covering the zero sensor case,
because the CCR O2 sensor code coverage was fairly limited.
It's entirely possible (even likely) that this migth break some existing
case: it tries to be a fairly direct ("stupid") translation of the old
code, but unlike the preparatory patch this does actually does change
some semantics.
For example, right now the git loader code assumes that if the git save
data contains a o2pressure entry, it just hardcodes the O2 sensor index
to 1.
In fact, one issue is going to simply be that our file formats do not
have that multiple sensor format, but instead had very clearly encoded
things as being the CCR O2 pressure sensor.
But this is hopefully close to usable, and I will need feedback (and
maybe test cases) from people who have existing CCR dives with pressure
data.

We currently carry two pressures around for all the samples and plot
info, but the second pressure is reserved for CCR dives as the O2
cylinder pressure.
That's kind of annoying when we *could* use it for regular sidemount
dives as the secondary pressure.
So start prepping for that instead: don't make it "pressure" and
"o2pressure", make it just be an array of two pressure values.
NOTE! This is purely mindless prepwork. It literally just does a
search-and-replace, keeping the exact same semantics, so "pressure[1]"
is still just O2 pressure.
But at some future date, we can now start using it for a second sensor
value for sidemount instead.
