Currently, the caller is responsible for not reusing a freed
weightsystem / cylinder or resetting the description field to
null. This is very unfriendly. Set the description field to null,
because that allows us to call free_* repeatedly on the same
object. Use the new behavior to make the weightsystem model code
a bit cleaner.

Since changes to the weight model are not modal anymore, nobody
queries the changed-flag. Remove it.

Implement the EditWeight undo command. Since there is common code
(storage of the old weight), this creates a common base class for
RemoveWeight and EditWeight. The model calls directly into the undo
command, which is somewhat unfortunate as it feels like a layering
violation. It's the easy thing to do for now.

The WSInfoDelegate (weight-system-info delegate) is used to display
a combo box of known weightsystem-types and auto-fills the weight if
the weightsystem-type is changed.
This would overwrite the weight data of the displayed dive when the
user hovers over the different entries. Moreover, it saves the original
weight in case the user cancels the editing action.
This is not viable when implementing undo of weightsystem changes,
because hovering over entries should not produce individual undo
commands. Instead, implement a special "temporary" row in the
weightsystem model. On canceling of the edit actions, simply reload
the weightsystem from the unmodified dive.

Before undoization, the WeightModel could be out-of-sync with
the actual dive and therefore had a row member variable. This
became redundant. Therefore, remove it.

There is only one caller of WeightModel::weightSystemAt() and that
certainly does not need a pointer into the weightsystem-table of
the current dive. Return a value type instead of a pointer.
This allows us to mark WeightModel::weightSystemAt() as const and
use it from WeightModel::data(). Slightly cleaner code.

This one is a bit more complicated than weight adding, because the
multiple-dive case is not well defined. If multiple dives are selected,
this implementation will search for weights that are identical to the
weight deleted in the currently shown dive. The position of the weight
in the list is ignored.

Introduce an AddWeight undo command. This is modelled after the
numerous dive-edit undo commands. The redo and undo actions are
connected to the WeightModel via two new signals, weightAdded
and weightRemoved.

The WeightModel always acted on the displayed dive. To support undo
of weightsystem changes, operate on an arbitrary dive. This is
in line with other models, where the updateDive() function resets
the model to represent a certain dive.

Change the remove() function of the cylinder and weight models
to take the index by value. The code used to take it by reference
and the reference would be invalidated when removing rows from
the model!

The current code of course works just fine. But there's a risk someone might
add something to one of these cases and not realize that there is an implicit
fall through going on. This is cleaner.

Replace the fixed-size weightsystem table by a dynamically
relocated table. Reuse the table-macros used in other parts
of the code.
The table stores weightsystem entries, not pointers to
weightsystems. Thus, ownership of the description string is
taken when adding a weightsystem. An extra function adds
a cloned weightsystem at the end of the table.

Since the default view is batched by trips, signals were sent trip-wise.
This seemed like a good idea at first, but when more and more parts used
these signals, it became a burden. Therefore push the batching to the
part of the code where it is needed: the trip view.
The divesAdded and divesDeleted are not yet converted, because these
are combined with trip addition/deletion. This should also be detangled,
but not now.
Since the dive-lists were sorted in the processByTrip function, the
dive-list model now does its own sorting. This will have to be
audited.

There is this anti-pattern in QModel data() functions to assign
to a "ret" variable and return at the end of the function. This
is inefficient, as the object is not directly constructed at
the space reserved by the caller.
Change the functions in WeightModel and CylinderModel to return
the objects directly.

When pasting (or undoing paste) the cylinders or weights may change.
Send the appropriate signals and update the models accordingly.
Currently, this means copying from current dive to displayed dive,
but hopefully we can get rid of "displayed_dive" in the not so
distant future.

Instead of a constant or a macro for the maximum
number of 'ws_info' elements the 100 literal was used.
Define MAX_WS_INFO in dive.h and use it everywhere.
Also clamp loops that iterate `ws_info' to MAX_WS_INFO.
Prevents potential out-of-bounds reading, similarly to
the previous commit about 'tank_info'.

helpers.h included qthelper.h and all functions declared in helpers.h
were defined in qthelper.h. Therefore fold the former into the latter,
since the split seems completely arbitrary.
While doing so, change the return-type of get_dc_nichname from

Replace constructs of the kind
s.toUtf8().data(),
s.toUtf8().constData(),
s.toLocal8Bit().data(),
s.toLocal8Bit.constData() or
qUtf8Printable(s)
by
qPrintable(s).
This is concise, consistent and - in principle - more performant than
the .data() versions.
Sadly, owing to a suboptimal implementation, qPrintable(s) currently
is a pessimization compared to s.toUtf8().data(). A fix is scheduled for
new Qt versions: https://codereview.qt-project.org/#/c/221331/

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.
