Add option to calculate the best mix portion of O2 and He for the dive's max
depth if the user enters * in the MOD and MND cylinder fields. Gas portions
are automatically recalculated if the max depth of the dive changes.

The switch depth of a decompression gas is its MOD. By renaming the heading to
"Deco MOD", it is more clearly distinguished from the bottom MOD, and it is
more obvious how they relate to the Bottom pO2 and Deco pO2 preferences.

Adds fields to the planner cylinder model for maximum operating depth (MOD)
for a bottom mix gas, and maximum narcotic depth (MND). Fields are read/write,
so changing MOD changes %O2 and vice-versa. Changing MND changes %He and
vice-versa.
When setting MOD directly, the %O2 is truncated (rounded down) to an integer,
which re-calculates the MOD, which is sometimes a few metres greater than the
input depth. This is desireable behaviour, as the rounding is conservative.

This fix is reasonably straightforward when the divedatapoint structure stores
the cylinder rather than gasmix.

Determining the correct cylinder index from a known gas mix can be
complicated, but it is trivial to look up the gasmix from the cylinder_t
structure.
It makes sense to remember which cylinder is being used. This simplifies
handling changing a cylinder's gas mix, either directly by the user, or
indirectly in the planner. It also permits tracking of multiple cylinders of
the same mix, e.g. independent twins / sidemount.

A few basic rules for gas validation:
We can't have <0%, or >100% of either O2 or He
O2 + He must not be >100%
Switch depth can't be <0%
This places limits on user-input values

This allows calculation and selection of best mix in the planner cylinder
entry, by entering the gas depth, followed by "b" for best (trimix) mix, or
"bn" for best nitrox mix.
The UI is not intuitive, but it is quick and easy. At the very least, it
should be documented.

If the value for "use" is negative or larger than the number of
elements in "enum cylinderuse", later CylindersModel::data() can
request a string in the lines of cylinderuse_text[cyl->cylinder_use],
which can SIGSEGV.

Having subsurface-core as a directory name really messes with
autocomplete and is obviously redundant. Simmilarly, qt-mobile caused an
autocomplete conflict and also was inconsistent with the desktop-widget
name for the directory containing the "other" UI.
And while cleaning up the resulting change in the path name for include
files, I decided to clean up those even more to make them consistent
overall.
This could have been handled in more commits, but since this requires a
make clean before the build, it seemed more sensible to do it all in one.

This is questionable, but perhaps useful.
When showing imperial cylinder sizes, show both the nominal value (with
no compensation for compressibility of the gas) and the "actual" amount
of gas the cylinder contains.
So an AL80 will show as a size of "80 (77)cuft", because while 80 is the
nominal size, the actual amount of gas that will fit is just 77 cuft.

We had two totally different usage cases for "get_volume_string()": one
that did the obvious "show this volume as a string", and one that tried
to show a cylinder size.
The function used a magic third argument (the working pressure of the
cylinder) to distinguish between the two cases, but it still got it
wrong.
A metric cylinder doesn't necessarily have a working pressure at all,
and the size is a wet size in liters. We'd pass in zero as the working
pressure, and if the volume units were set to cubic feet, the logic in
"get_volume_string()" would happily convert the metric wet size into the
wet size in cubic feet.
But that's completely wrong. An imperial cylinder size simply isn't a
wet size. If you don't have a working pressure, you cannot convert the
cylinder size to cubic feet. End of story.
So instead of having "get_volume_string()" have magical behavior
depending on working pressure, and getting it wrong anyway, just make
get_volume_string do a pure volume conversion, and create a whole new
function for showing the size of a cylinder.
Now, if the cylinder doesn't have a working pressure, we just show the
metric size, even if the user had asked for cubic feet.

Still trying to make it easier for the Mobile Port:
This patch is a bit bigger than I hopped, but it was the smallest that I
could get.
A lot of TODO items where added where I broke the code because the current
implementation would break the QML implementtion on the designer. I'll
most probably fix those myself when I finish the transition to the models
to the new folder.
I only moved both models at once because there's an interdependency
between them (seems inevitable, tough, but I'll take a better look at it
later).
