When selecting all dives via CTRL-A or manually and the trips
were not expanded, the QSelectionModel sends a single
selectionChanged signal per trip. We are reloading the map
in every call, making this very slow.
I couldn't figure out how to make QSelectionModel behave more
nicely, therefore I chose the nuclear option: Remove the map
reloading from selectionChanged() and hook into all functions
that do selection changes. In these functions, first call the
original code and then do the selection-changed operations.
This will certainly need some tuning.

Create a DiveFilter class that does the actual filtering.
Currently, mobile and desktop have their own version of this
class, though ultimately we may want to merge them.
The idea here is that the trip-model and undo-commands have
direct access to the filter-function and thus can take care
of keeping track of the number of shown dives, etc.

We used to only keep sites with dives around. This changed when

Instead of accessing the cylinder table directly, use the get_cylinder()
function. This gives less unwieldy expressions. But more importantly,
the function does bound checking. This is crucial for now as the code
hasn't be properly audited since the change to arbitrarily sized
cylinder tables. Accesses of invalid cylinder indexes may lead to
silent data-corruption that is sometimes not even noticed by
valgrind. Returning NULL instead of an invalid pointer will make
debugging much easier.

The tab was crashing if there were no cylinders because

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.

When keeping track of cylinder related data, the code was using
static arrays of MAX_CYLINDERS length. If we want to use dynamically
sized cylinder arrays, these have to be dynamically allocated.
In C++ code, this is trivial: simply replace the C-style arrays
by std::vector<>. Don't use QVector, as no reference counting or
COW semantics are needed here. These are purely local and unshared
arrays.

get_gas_used() returns the volume of used gases. Currently,

in the caller.

The ProfileWidget2::recalcCeiling() function is used in one place,
namely when an undo-command changes the mode. It recalculates
decompression data and repaints the ceilings and thus avoids a
full profile-redraw.
This is smart, but it becomes problematic when the dive is changed
and the ceiling is recalculated before the profile is redrawn.
The DivePlotDataModel then still has data from the previous dive
but cylinders of the new dive are accessed.
This kind of situation may arise if multiple dive fields are
updated, as for example when replanning a dive.
Currently, this only causes a temporary mis-calculation. When
removing MAX_CYLINDERS this will lead to crashes.
One might attempt to fix the whole data-dependency mess. This
commit goes the cheap route and simply redraws the profile when
the mode is changed. Yes, it is in a way ineffective, but we
do worse things. The ProfileWidget2::recalcCeiling() thus becomes
unused and is removed.

The native buffer of a membuffer is not NUL-terminated, so when you want
to detach it and use it as a C string, you had to first do
'mb_cstring()' that adds the proper termination/
This was all documented in the header files, and all but two users did
it correctly.
But there were those two users, and the exported interface was
unnecessarily hard to use. We do want the "just detach the raw buffer"
internally in the membuffer code, but let's not make the exported
interface be that hard to use.
So this switches the exported interface to be 'detach_cstring()', which
does that 'mb_cstring()' for you, and avoids the possibility that you'd
use a non-terminated memory buffer as a C string.
The old 'detach_buffer()' is now purely the internal membuffer
implementation, and not used by others.

The divesEdited signal sends the changed field as a parameter.
Since some undo-commands change multiple fields, this led to
numerous signals for a single command. This in turn would lead
to multiple profile-reloads and statistic recalculations.
Therefore, turn the enum into a bitfield. For simplicity,
provide a constructor that takes classical flags and turns
them into the bitfield. This is necessary because C-style
named initialization is only supported on C++20 onward!
Is this somewhat overengineered? Yes, maybe.
