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.

These were not optimal, because they would recalculate the current
dive and divecomputers for every invocation.

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.

For each selected dive that is hidden by the filter,
unselect_dive() was called, which led to a recalculation
of the current dive and divecomputer.
Instead, collect all deselected dives and deselect them
at the end. Thus, these calculations are performed
only once.

This tries to encapsulate the management of the current dive and
divecomputer in the selection code. The current dive is alreay
set by setSelection(). Add a new parameter to also set the
current divecomputer. If -1 is passed, then the current
computer number is remained. This will allow us to audit the code.
Because for now, the whole "current dive computer" thing seems
to be ill-defined.
This fixes a bug: the dive-computer number wasn't validated
when making a new dive the current dive. The new code has some
drawbacks though: when selecting a whole trip, the validation
will be called for all dives in the trip and thus the dive computer
number will depend on the dive with the lowest amount of dive
computers in the trip. This will need to be fixed.

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.

The DiveListView would touch the selection-innards directly.
Let's encapsulate that. Moreover, take care to reset the trip
selection when resetting the core data.

In analogy to dives add a selection flag for trips. The reason
being that search for a selected trip can be painfully slow when
we do it through Qt's proxy model.
Make sure to deselect trips when they are removed from the core.

Currently, selecting a single dive or deselecting all dives was
quite awkward: One had to pass in a single-dive vector and the
dive itself (as current dive). Provide a convenience function
that selects a single dive or deselects all dives if null is
passed in.

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.

Since we now have a selection.c translation unit, put the selection-
related functions there.

The file command_private.cpp had functions concerning selections
only. To make these functions accessible from outside the undo
machinery, turn it into a part of the core-library. Currently,
only C++ functions are exported. We might think about also
exporting a C interface.
