In DiveListView user actions (select-all, key-press,
mouse-release) were intercepted to send the selection-changed
signal if the selection changed.
However, with the recent cleanups, this can be done
directly from selectionChanged(), since in all cases (at
least the ones I tested), the part of the function that
is responsible for manual selection changes is called
only once.
This avoids quite some complex code flow.

The trip selection code was an awkward layering violation.
Whereas dive selections due to dive undo-commands trickled
down via DiveTripModel-->MultiFilterSortModel-->DiveListView,
for trip editing, the DiveListView directly intercepted the
TripEdited signal.
Instead, mimic the dive-selection code. This is a bit longer
but more consistent and logical. The undo/redo of trip changes
is now also a "programmatical" change of the selection.

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 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.

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.
Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
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 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.

Commit 2cea115ddb "fixed" the selection

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.

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.

For historic reasons, there where three distinct signals concerning
dive-selection from the undo-machinery:
1) divesSelected: sent newly selected dives
2) currentDiveChanged: sent if the current dive changed
3) selectionChanged: sent at the end of a command if either the selection
or the current dive changed
Since now the undo-commands do a full reset of the selection, merge these
three signals into a single signal.

Some commands tried to retain the current selection on undo/redo,
others set the selection to the modified dives.
The latter was introduced because it was easier in some cases, but
it is probably more user-friendly because the user gets feedback
on the change.

The DiveTripModel was used to represent both, trip and list views.
Thus many functions had conditionals checking for the current mode
and both modes had to be represented by the same data structure.
Instead, split the model in two and derive them from a base class,
which implements common functions and defines an interface.
The model can be switched by a call to resetModel(), which invalidates
any pointer obtained by instance(). This is quite surprising
behavior. To handle it, straighten out the control flow:
DiveListView --> MultiFilterSortModel --> DiveTripModelBase
Before, DiveListView accessed DiveTripModelBase directly.
A goal of this commit is to enable usage of the same model by mobile
and desktop.

to keep these as member variables. That would only risk

The DiveListView code had a very fundamental problem with its
header: Each had its own idea of who is responsible for sorting.
Since we can't easily change QHeaderView, accept QHeaderView
as the authority on sort-column and order.
To make this possible, split the reload() function in two
distinct functions:
- reload() reloads the model and sorts according to the
current sort criterion.
- setSortOrder() tells the header to display a certain
sort criterion. If this is a new criterion, it will then
emit a signal. In this signal, resort according to that
criterion.
Thus, the actual sorting code has to be moved from the
headerClicked() to a new sortIndicatorChanged() slot.
Morover, the sorting of the QHeaderView has to be used.

DiveListView::reload() was called for full reset of the dive list
and for changing the view (tree vs. lis) in DiveListView::headerClicked().
Since the latter does sorting by itself, a parameter "forceSort" was
introduced, which defaulted to true, but was set to false by
DiveListView::headerClicked().
To remove complexity, simply let DiveListView::headerClicked() set
the view by itself and remove tha parameter.

After invalidating the filter, the dive-selection was modified to
ensure that at least one dive is selected. This was done in the
filter code, but it seems preferrable to do this in the dive-list
code, which has direct access to the selection-model.
Therefore, move the code from MultiFilterSortModel to DiveListView.
While doing so, split the code in DiveListView into more functions to:
1) Get the index of the first dive (if any).
2) Select the first dive (if any).
This allows a distinct size reduction of conditional compilation
in MultiFilterSortModel (accesses to MainWindow are not possible
in mobile code).

Select the proper dives after the add, remove, split and merge
dives commands on undo *and* redo. Generally, select the added
dives. For undo of add, remember the pre-addition selection.
For redo of remove, select the closest dive to the first removed
dive.
The biggest part of the commit is the signal-interface between
the dive commands and the dive-list model and dive-list view.
This is done in two steps:
1) To the DiveTripModel in batches of trips. The dive trip model
transforms the dives into indices.
2) To the DiveListView. The DiveListView has to translate the
DiveTripModel indexes to actual indexes via its QSortFilterProxy-
model.
For code-reuse, derive all divelist-changing commands from a new base-class,
which has a flag that describes whether the divelist changed. The helper
functions which add and remove dives are made members of the base class and
set the flag is a selected dive is added or removed.
To properly detect when the current dive was deleted it
became necessary to turn the current dive from an index
to a pointer, because indices are not stable.
Unfortunately, in some cases an index was expected and these
places now have to transform the dive into an index. These
should be converted in due course.

In DiveListView, we have a very fundamental problem: When
On the one hand, we get informed of user-selection in the
DiveListView::selectionChanged() slot. This has to set the
correct flags in the C-backend.
On the other hand, sometimes we have to set the selection
programatically, e.g. when selecting a trip. This is done
by calling QItemSelectionModel::select().
But: this will *also* call into the above slot, in which
we can't tell whether it was a user interaction or an
internal call. This can lead to either infinite loops or
very inefficient behavior, because the current dive
is set numerous times.
The current code is aware of that and disconnects the
corresponding signal. This is scary, as these signals are
set internally by the model and view. Replace this
by a global "command executing" flag in DiveListNotifier.
The flag is set using a "marker" class, which resets the flag
once it goes out of scope (cf. RAII pattern).
In DiveListView, only process a selection if the flag is not
set. Otherwise simply call the QTreeView base class, to reflect
the new selection in the UI.
To have a common point for notifications of selection changes,
add such a signal to DiveListNotifier. This signal will be
used by the DiveListView as well as the Command-objects.

The currentDiveChanged signal was emitted by the DiveListView
to inform the MainWindow of a change of current dive. The
new current dive was passed as a parameter. The slot in MainWindow
then called select_dive() on the dive.
This seems pointless because:
1) In both emits, selected_dive dive was passed as argument. But
MainWindow can read this global variable itself.
2) Calling select_dive() again is a no-op, because obviously,
this already *was* the selected dive.
Moreover it seems conceptually wrong to set the current dive in the
slot that is informed of the change of the current dive.
