Split out the actual filtering from the MultiFilterSortModel.
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.

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.

We test for d being NULL so that's clearly an option we worried about, yet

When clicking "done" on the dive site edit screen, the diveSite
member variable was reset to nullptr in acceptChanges() at the
beginning of the function. This prevented posting an undo-command
as a consequence of the active widget losing focus.
Reset the diveSite variable after exiting dive-site mode, which
causes the active widget to lose focus.

Since requiring Qt >= 5.9.1, we can use the pointer-to-member-function

The application could be crashed by
1) Create dive site
2) Edit dive site
3) Undo until dive site is removed
4) Continue editing now non-existing dive site
Therefore, hook into the dive-site-deleted signal and if the
currently edited dive site is deleted, close the widget.
When closing the widget, make sure that the potentially
dangling pointer is reset to zero so that there is no
other potential use-after-free bug.

For historic reasons MapWidget::repopulateLabels() was called
in LocationInformationWidget::acceptChanges(). This should not
be necessary anymore, as this is done when entering/exiting
dive-site-mode.
Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
The LocationInformationWidget repopulated the map labels if the name
or location of a site changed. This is unnecessary because the
MapLocationModel catches these signals itself. Remove these calls.
As an added bonus, calling repopulateLabels() in QML context leads
to crashes later on. Therefore this should fix at least one
crash condition when dragging a flag on the map while the
dive-site-edit-tab is shown.

Clearing dive site did not work for two reasons:
1) We didn't get a signal when editing was finished.
2) When clearing the dive site, the "add new dive site" site was set.
Thus, connect to the editingFinished signal and in
DiveLocationLineEdit::currDiveSite() return a null pointer if
the string is empty.
This means that it is not possible to have a dive site with an
empty string, but that shouldn't be a problem, right?

The application state was encoded in a QByteArray. Thus, there was
no compile-time checking. Typos would lead to silent failures.
Turn the application state into an enum. Use the enum-class construct,
so that the values don't polute the global namespace. Moreover,
this makes them strongly typed, i.e. they don't auto-convert to
integers.
A disadvantage is that the enums now have to be cast to int
explicitly when used to index an array.
Replace two hash-maps in MainWindow to arrays of fixed sizes.
Move the application-state details into their own files.

On the main dive tab, add a button that opens the dive-site selection
widget showing all dive sites. This is done by setting the "temporary
dive site name" to the empty string. Thus no dive sites are filtered
and the "add new dive site" entries are not shown. Moreover, the
text is selected. The user can therefore immediately start typing to
activate the filter or enter the name of a new dive site.
The idea is that after downloading dives with GPS information the
user can select one of the close dive sites.

Currently, in the dive-site selection widget the distance to

When presenting the list of dive sites on the dive-info tab, sort
the dive sites by distance to the current dive. The idea is that
when the user wants to select a dive site, close dive sites should
be prioritized.
The location of the dive is determined with the dive_get_gps_location()
function introduced in the previous commit. This actual GPS data get
precedence over the currently set dive site for that dive.
On change of dive, the current location is updated in the
DiveLocationFilterProxyModel so that a potentially expensive search
for GPS data is not repeated for every comparison.

Since the dive-site-filter is active either on the dive-site-edit
page or the dive-site-list page, use that as the flag for dive-site-edit
mode. Moreover, when the filter is reset, the
MapWidgetHelper::reloadMapLocations() function is called, so we
can use that place to enter/exit edit mode.
This makes it easier to keep everything consistent.

The dive-site line edit box features two special entries for adding
new dive sites. These should display different texts depending on
whether the current dive has a dive site or not.

In the edit-dive-site tab the filter is switched to a particular

If we want to reuse this for the dive-site tab the mode has to

As long as a text field is active, CTRL-Z only affects this field.
Thus it is suprisingly hard to undo edits. There seems to be a
fundamental problem with CTRL-Z handling.
To make it somewhat easier, catch any ESC-key event and move the
focus to the MainWindow. This effectively removes the focus from
any text field.
This all appears very wrong, but so far I wasn't able to find the
root cause of the problem.

The signal was caught by the MainWindow to:
1) call setDefaultState()
2) call refreshDisplay()
3) call refreshDisplayedDiveSite()
1) Let's call that directly from the widget. The reason is that in
the future there might be multiple way to get into the widget and
therefore the widget needs finer control.
2) Remove this call as it produces an unsteady UI.
3) This should be done by undo commands, not only when finishing
dive site editing.
Thus, the signal becomes unnecessary and can be removed.

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.

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.

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.
