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.

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.

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
the pressure at which the diver should be back at the surface. This
pressure was hardcoded to bar.

Apparently, it can happen that the default cylinder is not set
even though same_string(prefs.default_cylinder, "") is false.
Then we fall back to the 11.1l air cylinder.

void DivePlannerPointsModel::setupCylinders() in diveplannermodel.cpp
handles setting up cylinders for the planner. If there is a current
dive, cylinders form that dive are copied. Otherwise the default
cylinder is added and lacking that a standard size cylinder.
If the current dive does not have any cylinders, we could end up
without cylinders. This patch adds a test for this case and delegates
to the other two sources of a cylinder in that case.

I have manually added dives from an ancient version of Subsurface.
Trying to edit these caused Subsurface to crash due to comparison of
string of dc.model that did not exist (to a static string). And further
down the execution path we were crashing as there were no samples
associated with the dive.

Read and use the last_stop preference in the plan function.
Read the plan notes preferences and set variables (plan_verbatim,
plan_display_runtime, plan_display_duration, and plan_display_transitions)
in the add_plan_to_notes function. Don't read the preferences and set
variables otherwise. Both plan and add_plan_to_notes functions are called
on data change.
Previous behaviour was:
- Set variables on declaration
- Reset variables in plan function (even variables that only relate to
planner notes output)
- Changing a preference triggered set_xxx function which sets variable,
then plan function, which sets variable again.
Apart from being inefficient, the previous behaviour made it difficult to
track down where and when variables were set.

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).
