This includes using the C++ version of membuffer. There appears
to not have been a leak, because the buffer is freed in
flush_buffer(), but usage was somewhat inconsistent and hard to
follow.
Also, convert some string handling to std::string to avoid free()
madness.

This changes default behavior when creating a sample struct
in C++ code: it is now initialized to default values. If this
ever turns out to be a performance problem, we can either add
additional constructors or use special functions that do
not initialize memory, such as make_unique_for_overwrite.
This removes non-standard (respectively >C++20) constructs,
namely designated initializers.

Long term project: convert core to C++ so that we can
use higer-level constructs, notably std::vector<>.
This does not change any code - only fixes compile issues.
Mostly casting of (void *) to the proper type. Also designated
initialization of the sample struct had to be rearranged.

The undo-code uses owning pointers based on std::unique_ptr to
manage lifetime of C-objects. Since these are generally useful,
move them from the undo-code to the core-code. In fact, this
eliminates one instance of code duplication.

The parser API was very annoying, as a number of tables
to-be-filled were passed in as pointers. The goal of this
commit is to collect all these tables in a single struct.
This should make it (more or less) clear what is actually
written into the divelog files.
Moreover, it should now be rather easy to search for
instances, where the global logfile is accessed (and it
turns out that there are many!).
The divelog struct does not contain the tables as substructs,
but only collects pointers. The idea is that the "divelog.h"
file can be included without all the other files describing
the numerous tables.
To make it easier to use from C++ parts of the code, the
struct implements a constructor and a destructor. Sadly,
we can't use smart pointers, since the pointers are accessed
from C code. Therfore the constructor and destructor are
quite complex.
The whole commit is large, but was mostly an automatic
conversion.
One oddity of note: the divelog structure also contains
the "autogroup" flag, since that is saved in the divelog.
This actually fixes a bug: Before, when importing dives
from a different log, the autogroup flag was overwritten.
This was probably not intended and does not happen anymore.

The moveInVector() function was defined in qthelper.h, even
though it has nothing to do with Qt. Therefore, move it into
its own header.
Morover, since it is a very low-level function, use snake_case.
And rename it to move_in_range(), because it does not only
work on vectors, but any range with random-access iterators.

We have a prevailing problem with global QObjects defined as
static global variables. These get destructed after main()
exits, which means that the QApplication object does not
exist anymore. This more often than not leads to crashes.
In a quick search I didn't find a mechanism to register
objects for deletion with QApplication. Therefore, let's
do our own list of global objects that get destructed
before destroying the QApplication.

For better scalability, we might replace the dive event icons

The tissue percentages were realized as 16 independent polygons.
That didn't work at all with the new absolute scaling.
Reimplement the item and blast it onto a pixmap. Not only is
this artifact-free, it also should (hopefully) be quite a bit
more efficient than painting numerous lines.
In contrast to the old code, this does access the plot_info
structure directly instead of using the model. Not so much
for performance reason, but rather to make things more robust:
We have a strongly typed language. Why would we shoehorn data
through the weakly typed QVariant and mess with wierd
index-arithmetics. Makes no sense to me. Qt-model have to
be used for interfacing with Qt. They are terrible for
intra-application data transfer.

Since there (currently) is no interactive widget on mobile, there
is no point in compiling it. This was a bit more complicated than
expected, since there were other source files (divehandler.cpp
and ruleritem.cpp) which reference ProfileWidget2 and therefore
need to be removed. Otherwise, the dreadful MOC produces unresolved
references.
We could now remove all the conditional compiles in
profilewidget2.cpp, but let's keep them for now. We might have
to readd a number of them later, when making the mobile-profile
interactive.

This simply subclasses QGraphicsScene and is used as

C-style memory management is a pain and nearly nobody seems to get
it right. Add a C++-version of membuffer that frees the buffer
when it gets out-of-scope. Originally, I was thinking about
conditionally adding a constructor/destructor pair when compiling
with C++. But then decided to create a derived class membufferpp,
because it would be extremely confusing to have behavioral change
when changing a source from from C to C++ or vice-versa.
Also add a comment about the dangers of returned pointer: They
become dangling on changes to the membuffer.

The application state is a desktop-only thing. The mobile UI
also has its application state, but that is something completely
different.
The last remaining user of the application state was to flag
whether the planner is active. Since this has all been
unglobalized, the ApplicationState structure can be moved
from core to the desktop UI. And there it can be made local
to the MainWindow class.

Up to now, we passed a "shiftPressed" flag to the individual
selection functions. To be more general replace by a struct
with "shift" and "ctrl" flags.
While doing this:
1) Move the struct into a new statsselection file for better
encapsulation.
2) Change shift to control in the scatter series, since individual
selection of items is usually done with control, not shift.
Shift usually means "select range".

Slowly converting the QGraphicsScene items to QSGNodes to
avoid full replot of the scene.
This adds a new abstraction for line-nodes. Since the render()
function here is fundamentally different from the pixmap-nodes
we had so far, this has to be made virtual.
Also, move the quartile markers to their own source file,
since the StatsView source file is quite huge already.

In order not to waste CPU by constantly rerendering the chart,
we must use these weird OpenGL QSGNode things. The interface
is appallingly low-level and unfriendly.
As a first test, try to convert the legend. Create a wrapper
class that represents a rectangular item with a texture
and that will certainly need some (lots of) optimization.
Make sure that all low-level QSG-objects are only accessed
in the rendering thread. This means that the wrapper has
to maintain a notion of "dirtiness" of the state. I.e.
which part of the QSG-objects have to be modified.
From the low-level wrapper derive a class that draws a rounded
rectangle for every resize. The child class of that must then
paint on the rectangle after every resize.
That looks all not very fortunate, but it displays a
legend and will make it possible to move the legend
without and drawing operations, only shifting around
an OpenGL surface.
The render thread goes through all chart-items and
rerenders them if dirty. Currently, on deletion
of these items, this list is not reset. I.e. currently
it is not supported to remove individual items.
Only the full scene can be cleared!
