In the list view two functions were still manually collecting
the selected dives. Use getDiveSelection() there as well.
Careful: that means that the check for dives that are already
outside of a trip now has to be done in the RemoveDivesFromTrip
command.

The main window called a function to init the header actions
(i.e. the context menu) of the dive-list. There is no reason why
this shouldn't be done in the constructor of the dive list, since
it only accesses the QSettings, which are available at application
startup. This improves modularity of the code (by a tiny, tiny bit).
Moreover, the initialization function was at the same time the
header-reloading function. That function can now be folded
into the settings-changed function, since that is the only
remaining user.

So far, the PreferencesDialog emitted a settingsChanged signal.
This meant that models that listened to that signal had to
conditionally compile out the code for mobile or the connection
had to be made in MainWindow.
Instead, introduce a global signal that does this and move
the connects to the listeners to remove inter-dependencies.

getDiveSelection() returns a vector of the selected dives.
Use that instead of looping over the dive table and checking
manually.
This removes a few lines of code.

The UI only allowed adding dives to trips above or below the
current dive (and even that is buggy). This is a strange
restriction, since trips are designed to be non-contiguous.
Allow adding dives to any trip using the new trip selection
dialog. The undo-command is already there, so only little
code to write.
This feature was requested on the mailing list.

In the dive list we have horrible code, which intercepts all events
to save the selection before/after the event. This was necessary
because we couldn't get Qt's selection data flow under control.
This means intercepting all events that can change the selection.
The page-up, page-down, home and end keys were forgotten. Add these
cases.
Fixes #2957.

There is no reason that this dialog is a singleton. Since it is modal,
it can be created on demand. Apart from removing superfluous global state,
this simplifies code, because preparing the widget can now be done in
the constructor instead of overriding the showEvent() function.

This one is a bit hairy, because two things might happen if the
picture has a geo location:
- A dive gets a newly generated dive site set.
- The dive site of a dive is edited.
Therefore the undo command has to store keep track of that.
Oh my.

If we want to make addition of pictures undoable, then create_picture()
must not add directly to the dive. Instead, return the dive to which the
picture should be added and let the caller perform the addition.
This means that the picture-test has to be adapted.

The DiveListView had a singleSelectedTrip function that
returns the selected trip if exactly one trip is selected.
This could be very slow if numerous non-trip items were
selected, because all the selection indices were back-
translated by the proxy model.
This could make selection changes very slow, because the
MainTab used said function to determine whether it should
show trip or dive data.. Indeed, with a 3500 dive test log,
when selecting all dives in tree mode, the updating of the
TabWidgets is sped up from 130 ms to 5 ms this commit.

To check wether the tab widgets should show the trip view, they called
the selectedTrips() function. The trip view was shown if that contained
only one trip. However, the selectedTrips() function was very slow,
because it has to query to core models.
Change the function to singleSelectedTrip(), which returns a trip
if there is exactly one trip selected. The function returns early
if there is more than one trip selected. This makes the select-all
case much faster.
There are two cases which are still very slow:
- List mode, because here all top-level items are queried.
- Dive log with many only top-level items.
Ultimately, we will have to cache the trip selection because
querying the model is too slow.

The old code would call QItemSelectionModel::select() once for every dive.
Instead collect the selection in a QItemSelection and only call
QItemSelectionModel::select() once. This makes selecting multiple dives
significantly faster.
The loop also expanded the trips with selections. This has now to be
done in an extra loop.

When determining the selected dive sites to highlight them on the
map, the DiveListView code used the local indices of the selected
dives. However, that was unreasonably slow. Even though a layering
violation, let's access the core data structures directly. In my
tests this improved from 700 ms to 0 ms!

The DiveListView widget has to differentiate between programmatical
und user-initiated selection changes. It did so by using the
DiveListNotifier::inCommand() flag.
However,
1) There is only one point of entry for such selection changes,
viz. the MultiFilterSortModel::selectionChanged() signal
2) This signal is not only emitted in command-context.
Another source is for example dive-map selection changes.
Therefore, move the programmatical-selection-change status down
to the widget and set/reset it in the diveSelectionChanged() slot.
This makes "select all visible dive sites" somewhat faster. Sadly,
not as much as expected.

This was erroneous, as it should only be called at the end of
a selection change, not after every single dive. It made selection

This appears to be an artifact. Collapsing does not unselect
the current dive, so reselecting it appears pointless.
Also it is unclear why the selection should be restricted to
a single dive after collapsing.
Probably that was originally meant to expand only the trip
with the current dive in it?

Commit 2cea115ddb7528d9e6dd1bf918ebf5c670b82479 "fixed" the selection
by hooking into mouseRelease events. An unintended consequence was
that scrolling with the cursor keys didn't update the current dive.
Therefore, also hook into the corresponding key-press events.
This is just horrible, but I'm not aware of any possibility to fix
it properly.

Fix two issues:
1) When narrowing the selection, we didn't get setSelection()
calls. Only, when the user released the mouse button was
the selection updated. Therefore, hook into the mouse-release-
event and update the UI if the selection changed.
2) We updated the ui in setSelection(). However, this was called
on mouse-move even if the actual selection didn't change.
Therefore, compare selection before and after processing of
the event and only refresh the UI if there are changes.
Clearly, this can only be a quick stopgap solution and we
should find out how to properly hook into the selection change
machinery. Though see commit 4928c4ae0421193bbd371cb0924091a970489611
for the reason why we do things as we do them.

After selecting dives, the selected dive sites are collected.
This was done using the selectionModel()->selection().indexes(),
which is wrong, because it gives one index per row *and* column.
Accordingly, every dive site was added numerous times to the
array of dive sites to be selected. Change this to
selectionModel()->selectedRows(), which gives one entry per row.
Moreover, if multiple dives with the same site were selected,
this site was also added to the array multiple times. Therefore,
check the array before adding sites.
Note that all this should not change the user experience in
any way, it is only a code-hygiene thing.

The QList served as backing store for backupExpandedRows()
and restoreExpandedRows(). However, these always came in
pairs in the same scope. There is no reason to store the
expanded rows over a longer time.
Therefore, return the expanded rows from backupExpandedRows()
and take them as argument in restoreExpandedRows(). Morover
replace the QList<int> by the much lighter std::vector<int>.
We certainly don't need copy-on-write, reference-counting and
immutability of iterators in this case.

The DiveListView caught signals from the DiveTripModel
with the corresponding indexes. However, the DiveListView
is actually connected to the MultiFilterSortModel and
thus has to translate the indexes.
Instead, catch the signals in the MultiFilterSortModel,
transform them and resend. Let the DiveListView get
its signal from the MultiFilterSortModel.
Yes, this makes things less efficient because there is
an extra signal. On the upside, the makes data-flow much
more logical. Selection will have to be fixed anyway.

The goal here is to unify desktop and mobile by moving
selection code from the desktop-only view.
Currently, initialization of the selection still has to be

The DiveListView has a function to select the first dive. Move
this to the core to be able to call it from all parts (not only
desktop) of the code.
Currently, this has a (small?) UI regression: when filtering dives
and no selected dive is visible anymore, the old code would select
the first dive in the list. The new code selects the newest dive,
which might not be the first if some sort-criterion is active.
To revert to the old behavior, it will be necessary to move the
sorting function likewise to the core.

When selecting all dives via CTRL-A or manually and the trips
were not expanded, the QSelectionModel sends a single
selectionChanged signal per trip. We are reloading the map
in every call, making this very slow.
I couldn't figure out how to make QSelectionModel behave more
nicely, therefore I chose the nuclear option: Remove the map
reloading from selectionChanged() and hook into all functions
that do selection changes. In these functions, first call the
original code and then do the selection-changed operations.
This will certainly need some tuning.

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.
