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 map widget called the dive list to select dives. This is
inconsistent and complex. The dive list has to call down to
the core anyway. Therefore, change the code to call the common
core function.
This means that we have to transform integer ids into dive-pointers.
That is a bit sad, because the dives were just transformed into
indices. Let's address that in a future commit.

In the future we might want to use undo-commands for mobile as
well (even if not implementing undo).
Therefore, move the undo-command source from desktop-widgets
to their own commands top-level folder.
Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
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.

There is the alternative MapWidget::reload() function, which
centers on the selected dive-site.
Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
When clicking a dive site on the map, the QML code would set
the selected dive site, but then all dives of dive sites in
the vicinity were set. But still only the clicked-on dive site
was shown.
Therefore, don't set the list of selected dive sites in QML,
but later in DiveListView::selectDives(), where we know all
the dives that were selected.
This, again, gives nasty entanglement of diverse widgets and
models.

When changing the selection the MapLocationModel was reset.
This lead to crashes on Qt-5.9 which are due to QML accessing
data that was freed during model reset. This putative Qt bug
doesn't happen on newer Qt versions. At least Qt-5.12 is known
to work.
Instead of fighting the bug, let's simply not reset the model
but send a dataChanged() for every element of the MapLocationModel.
Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
Experimentation has shown that the image of a flag will
only be changed after dataChanged() if it is a simple
property. The old code had a complex QML expression and
then - for some reason - it didn't work.
To give us better control over the flags and avoid full
reloads of the map therefore introduce a model-property
pixmap name. The name depends on whether the site is
selected and if not, whether we are in divesite-edit mode.
This makes the code rather convoluted. Firstly, we have
to save whether the site is selected in the map-item.
Secondly we have to access the global map-widget, which
in turn has to go to the map-widget helper (layering
violation!).

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.

Since the dive-site-filter is active either on the dive-site-edit

DiveListView::selectDives() would only select new dives but not clear

During edit mode, we could get spurious reload() requests owing
to tabs being hidden. This led to undefined behavior:
In some cases entering dive site edit mode would show all dive
sites, in some only the dive site of the currently edited dive.
Therefore, refuse to reload the map while in edit mode. The
corresponding flag already exists.

On reload of the map, the map exits edit mode. Sounds logical
at first, but the whole map-mode code is very unpredictable.
What happened was that when switching from the dive site table
to dive site edit mode, the code would enter map edit mode first.
Then, the dive site tab got its hide-signal, which would reset the
filter. This would reload the map and thus exit mode. Hence the user
can't drag the flag on the map.

There was this ugly pattern of passing pointers-to-dive_site via
a QVariant of void * type. This is of course inherently unsafe.
Pass these pointers using their proper types instead. This makes
it necessary to register them in Qt's meta-type system. Doing so,
fixes a bug: QML couldn't call into updateDiveSiteCoordinates()
because it didn't know the type and thus the coordinates of
the moved flag were not reflected in the divesite-dialog.

Replace UUIDs from LocationInformationModel and fix the fallout.
Notably, replace the UUID "column" by a DIVESITE "column".
Getting pointers through Qt's QVariant is horrible, we'll have
to think about a better solution.
RECENTLY_ADDED_DIVESITE now defines to a special pointer to
struct dive_site (defined as ~0).
This fixes an interesting logic bug:
The old code checked the uuid of the LocationInformationModel (currUuid)
for the value "1", which corresponded to RECENTLY_ADDED_DIVESITE.
If equal, currType would be set to NEW_DIVE_SITE. Later, _currType_
was compared against _RECENTLY_ADDED_DIVESITE_. This would only work
because NEW_DIVE_SITE and RECENTLY_ADDED_DIVESITE both were defined
as 1.

The keeps track of different sub widgets needed by other parts
of the code, notably:
MainTab
PlannerDetails
PlannerSettingsWidget
ProfileWidget2
DivePlannerWidget
DiveListView
Access to these widgets was provided with accessor functions.
Now these functions were very weird: instead of simply returning
pointers that were stored in the class, they accessed a data
structure which describes the different application states.
But this data structure was "duck-typed", so there was an
implicit agreement at which position the pointers to the
widgets were put inside. The widgets were then down-cast by
the accessor functions. This might make sense if the individual
widgets could for some reason be replaced by other widgets
[dynamic plugins?], but even then it would be strange, as one
would expect to get a pointer to some base class.
Therefore, directly store the properly typed pointers to the
widgets and simply remove the accessor functions. Why bother?

The setEditMode(bool) function behaves very differently, when

Since setEditMode() doesn't exist anymore, turn the editMode
Q_PROPERTY line to the MEMBER version. Accordingly, remove
the reader function. If QML wants to enter edit mode, it
should invoke the appropriate function and not simply set

This was used by LocationInformationWidget to instruct the map
that the coordinates of the current dive site has changed.
There is no reason why this couldn't be a function call, as no
other object ever connect()s to this signal. In fact, such a
function already exists viz. updateLocationOnMap.
Therefore, replace the signal by a simple function call.
Moreover, the uuid and coordinates of the dive site were transported

information in the parameters of the function. This makes it

The dive site list was connected to centerOnDiveSite(). Apparently,
the currently selected dive site should have been shown in the map.
Yet, this never worked, because the actual dive site of the selected
dive had precedence in centerOnDiveSite().
It seems that centerOnDiveSite() had actually to purposes:
1) center on the passed in dive site
2) center on the dive sites of the selected dives
Therefore, split this function in two separate functions for
each of these use-cases. This allows us to remove some pre-processor
magic (mobile vs. desktop) and to remove a parameter from the
MainTab::diveSiteChanged() signal.

If the QML modules for QtLocation and QtPositioning are

load another QML which is for showing a red error text

If the map QML has failed, use a macro in all relevant
