Subsurface uses "local time" which in particular means we never
display time zone information to the user. The user (and our file
format) only sees times like 5pm or 17:00. A better name than
local time (which could mean "local at the dive spot) would
be "watch time", the time displayed by the diver's watch when
she entered the water.
Internally, we store times as time_t, seconds since Jan 1 1970 0:00
UTC. Our convention for conversion between 5pm and time_t as always
been to treat 5pm as if it were UTC.
Then confusion arose since Qt's QDateTime (which is tied to UI elements
like QTimeEdit and similar) is time zone aware and by default assumes
the system time zone. So when we set a QDateTime to 5pm and then later
convert it to time_t we have to take care about the difference between
UTC and the system time zone.
This patch unifies our solution to this problem: With it, we set all
QDateTime's time zone to UTC. This means we don't have to correct for
a time zone anymore when converting to time_t (note, however, the
signedness issue: Qt's idea of time_t is broken since it assumes it
to be unsigned thus not allowing for dates before 1970. Better use the
millisecont variants).
We only need to be careful about time zones when using the current time.
With this convention, when assigning the current time to a QDateTime, we
need to shift for the time zone since its value in UTC should actually be
the watch time of the user who is most likely used to the system time zone.

Since 6cd711a1 filters don't work. This went unnoticed because the
commit wasn't applied on v4.5-branch.
Partially reverting it makes filters work again.

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.

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.

Most of the time we are adding all the dives, so do this in a single model
operation. This makes the case when adding a single dive (in the undo delete
function) slightly more complicated, but that seems totally worth it for the
speedup in the common case.

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.

In the planner, for recreational mode, there is a setting indicating

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.

It's possible that this will create an out of order dive list, but it
seems the most consistent way to do things and to avoid more than one dive
with the same dive number (which could have happened if you add several
dives manually that are not the newest dives in the dive list).
