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.

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.

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.

This one is a bit hairy, because two things might happen if the

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.

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

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 appears to be an artifact. Collapsing does not unselect

Commit 2cea115ddb "fixed" the selection
by hooking into mouseRelease events. An unintended consequence was
that scrolling with the cursor keys didn't update the current dive.

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 4928c4ae04
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()

pairs in the same scope. There is no reason to store the

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

The DiveListView caught signals from the DiveTripModel
with the corresponding indexes. However, the DiveListView
is actually connected to the MultiFilterSortModel and

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

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

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.
