Q_FOREACH and foreach are anachronisms.
Range based for may cause a performance regression: it can
lead to a copy of shared containers (one reason why Qt's
COW containers are broken). However, as long as there is no
user noticeable delay, there is no point in analyzing each case.
And also no point in slapping an 'asConst' on every container
that is looped over.

printf() is a horrible interface as it does no type checking.
Let's at least use the compiler to check format strings and
arguments. This obviously doesn't work for translated strings
and using report_error on translated strings is dubious. But OK.

Unfortunately Coverity doesn't understand that most Qt data

it is the way it is. Thus, passing by value is not an issue.
Out of ca. 25 warnings only two were legit. Let's silence
the others by either std::move()ing or passing by reference,
as would be idiomatic C++, which Qt is not.

The signals/slot names for dive selection changes were a mess.
Unify on divesSelected(). Firstly, selectionChanged() is a Qt
thing. Secondly, it is consistent with tripSelected().

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.

When manually selecting a trip, the selectionChanged()
virtual function was manually selecting the dives of the
trip and thus ultimately recurse into itself.
So far this seems to work OK, but better to avoid this
recursion by setting the programmaticalSelectionChange
flag.
I'd like to send the selection-changed signal directly
from selectionChanged() and this recursion would lead
to double signals.

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.

After sending a selection-change signal, there follows a current
dive changed signal. Combine these two into a single signal, since

Each of these calls recalculates the current dive and divecomputer.
Instead, collect the dives to be selected/deselected and (de)select
them at once.
This needs some code refactoring in the core, because we need a
function that
1) doesn't send a signal by itself.
2) doesn't clear the trip-selection.
This contains some reorganization of the selection functions
signatures: The filter code is the only caller that keeps the
selected dive and the only caller that cares about whether the
current dive changed. So let only the function that keeps the
selected dive return whether the current dive changed.
It's all very fragile.

Users report that the ShiftTimesDialog does not work on Mac and
Windows. Apparently, get_first_selected_dive returns NULL, which
should not be possible because the dialog is only created when
dives are selected. Very omninous.
Get the selected dives in the caller and pass them down. This
bug at least should not happen anylonger. Perhaps now the
dialog does not show at all, but that will narrow down the
root cause of the problem.

Commit e42fc1a1e9 introduced a
crash condition. Apparently the code attempts to test whether
the clicked-on item is a top-level dive. The "Collapse others"
menu item should not be shown in that case. It does this by
testing "d->divetrip". However, "d" might quite logically be
null if clicking on an unexpanded trip header.
Therefore, check explicitly for the trip header case (which
should show the menu item) and for good measure prevent
the nullpointer access (that should be caught by testing
for trip, but who knows).

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 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.

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.
