To remove reliance on global state, pass an "in_planner" argument
to decoMode(). Thus, calls to in_planner() can be removed.
This is a more-or-less automated change. Ultimately it would
probably be better to pass the current deco-mode to the affected
functions instead of calling decoMode() with an in_planner

The DiveHandler shows a context menu where a cylinder can be
chosen. This indirectly accesses the global displayed_dive

Remove this in a step to make the profile reentrant.
The code was quite ominous: instead of simply generating the

with Qt's cumbersome model/view API. All this trampling over
global state can be removed by simply making the function
that generates the list globally accessible.

To reset the core data structures, the mobile and desktop UIs
were calling into the dive-list models, which then reset the
core data structures, themselves and the unrelated
locationinformation model. The UI code then reset various other
things, such as the TankInformation model or the map. . This was
unsatisfying from a control-flow perspective, as the models should
display the core data, not act on it. Moreover, this meant lots
of intricate intermodule-dependencies.
Thus, straighten up the control flow: give the C core the
possibility to send a "all data reset" event. And do that
in those functions that reset the core data structures.
Let each module react to this event by itself. This removes
inter-module dependencies. For example, the MainWindow now
doesn't have to reset the TankInfoModel or the MapWidget.
Then, to reset the core data structures, let the UI code
simply directly call the respective core functions.

The Bühlmann factors were cached in a thread-safe hashmap. It seemed

Indeed, in a very cache friendly test (16 entries, tight loop) calling the
factor() function 32 000 000 times from a different translation units we get:
- with cache: 604 ms
- without cache: 266 ms

Instead of using fixed size arrays, use a new cylinder_table structure.
The code copies the weightsystem code, but is significantly more complex
because cylinders are such an integral part of the core.
Two functions to access the cylinders were added:
get_cylinder() and get_or_create_cylinder()
The former does a simple array access and supposes that the cylinder
exists. The latter is used by the parser(s) and if a cylinder with
the given id does not exist, cylinders up to that id are generated.
One point will make C programmers cringe: the cylinder structure is
passed by value. This is due to the way the table-macros work. A
refactoring of the table macros is planned. It has to be noted that
the size of a cylinder_t is 64 bytes, i.e. 8 long words on a 64-bit
architecture, so passing on the stack is probably not even significantly
slower than passing as reference.

The purpose of the gettextFromC class is twofold:
1) It provides a static storage of C strings if the C part needs
a translation and doesn't want to deal with memory-management.
2) It severs as a catch-all class for translations that do not come
from a proper class (i.e. from helper functions).
The second case was used a few times in qthelper.cpp. By using the
trGettext() function, a cached C-string was obtained. But in every
single instance, this C-string was then back-converted into a QString.
Therefore, use the gettextFromC::tr() function directly, which
returns a QString. Not only is the resulting code simpler - this also
avoids superfluous caching of translation strings.

When adding a picture to a dive, cache_picture() was called, which
calculated the hash of the picture in a background-thread.
This made tests occasionally fail, because the tests depended on
the filename-to-localfilename being overwritten in a call running
in a different thread. Depending on which thread finished first,
the test succeeded or failed.
The easiest way to circumvent this problem is to remove the cache_picture()
call. The hash will be calculated anyway with the thumbnails. And
the only function of the hash is the "find moved images" function. Which
is not an issue here, because the user just loaded the images from

qthelper.cpp is already quite voluminous. Move the recently
introduced localized versions of (v)snprintf() and put_format()
into their own translation unit.
Moreover, adopt C-style semantics for asprintf_loc(). This function
will be used to remove fixed-size buffers in core/plannernotes.c.
