Recently we changed the MapLocationModel-items to store whether
they are selected. Thus, we can directly export an isSelected
flag instead of calling a function taking a dive-site argument.
1) This makes the QML easier to read.
2) This avoids passing pointers through QML which has caused
us lots of pain.

Since not fully reloading the map on selection change,

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!).

When clicking on a flag
1) The QML would call MapLocationModel::setSelected() with
fromClick = true
2) MapLocationModel::setSelected() would emit a signal
selectedLocationChanged()
3) MapWidgetHelper would catch that signal and do the actual
processing.
Other functions would call MapLocationModel::setSelected() with
fromClick = false, which would not emit the selectedLocationChanged()
signal.
Detangle this a bit by calling the selectedLocationChanged() function
directly from QML and remove the fromClick parameter.

There weree two functions in MapWidgetHelper: one to enter and
one to exit edit mode. Both functions set the flag and emitted
a signal if the flag had changed.
Since the edit mode only depends on a flag of the filter this
can be simplified to a simple function that updates the flag
and raises the signal if the flag changed.

Just to be sure, refuse to add null divesites to the selection.

Currently, dive site names are only updated on full reload.
Instead hook directly into the corresponding signal in the

printGPSCoords() returned a newly allocated C-style string. Most
callers simply made a QString out of it and freed the C-style string.
This is paradoxical, as printGPSCoords internally works with QStrings
and converts them to C-style on return.
Therefore, let printGPSCoords() return a QString and create a
printGPSCoordsC() wrapper for the two C-callers.
Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
The printGPSCoords() function returns a copied C-style string. Since
the owndership is transferred to the caller, the correct return type
is "char *" instead of "const char *".
Thus a number of casts when calling free can be removed.
Moreover a number of callers didn't free the string and thus were
leaking memory. Fix them. Ultimately we might want two versions
of the function: one for QString, one for C-style strings.

This was used by LocationInformationWidget to instruct the map

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

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.
