getFormattedCylinder() is a helper function to format a list
of cylinders. It had that weird logic that it would skip
cylinders without description unless it is the first, which
would instead be written as "unkown".
The reason was the old statically sized cylinder array,
where it wasn't clear if a cylinder was actually in use.
This became obsolete when switching to a variable size
cylinder array. Firstly, all cylinders in the array were added
by the user. Secondly, we now also support dives without
cylinders, i.e. the first cylinder is not any different from
the rest.
Thus, remove the logic and format any cylinder without
description as being of type "unknown".

Move this function from maintab.cpp to qthelper.cpp. Since the
functionality was used in numerous places, use the helper function
there as well. This removes a number of inconsistencies. For example,
sometime setTimeSpec(Qt::UTC) was called, even though the
QDateTime object was already created with that time spec.

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.

Even though the functionality is seemingly trivial, this is a bit

2) React to changes to the divelist

Add a DiveListNotifer::eventsChanged signal, which is emitted when
the events changed. This is very coarse, at it doesn't differentiate
between signal addition / editing / deletion. We might want to
be finer in the future.
Catch the signal in the profile-widget to replot the dive if this
is the currently displayed dive. Reuse the cylindersChanged() slot,
but rename it to the now more appropriate profileChanged().

The diveListNotifier.divesSelected() signal is used to inform the

sets current_dive just before sending the signal. Remove the

Implement the EditWeight undo command. Since there is common code

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.

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 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.

and add the corresponding switch-case.

Instead of handing a reference-to-dive to QML, prerender all the needed
properties and store them as values in DiveObjectHelper. Exception:
- date(): generated from timestamp
- time(): generated from timestamp
- cylinderList(): does not depend on dive anyway and should be made
static.
This hopefully avoids the random mobile crashes that we are seeing.
Clearly, this code needs to be optimized, but it is a start.

DiveObjectHelper is a tiny wrapper around dive * to allow access

CylinderObjectHelper is used for structured formatting of cylinder
values in grantlee types. Instead of keeping a reference to a
cylinder, turn it into a value type containing the formatted strings.
This should be distinctly safer, as we don't risk having stale
references flying around. Moreover, we don't have to use pointers
but can use containers containing plain CylinderObjectHelper. Thus,
no explicit memory management is needed, making the code distinctly
easier to understand.
Sadly, currently grantlee does not support Q_GADGET based Q_PROPERTY.
Therefore a GRANTLEE_*_LOOKUP block has to be added. This can be
removed in due course, as a patch to remedy this issue is in current
grantlee master.
