8581e213ed selection: trickle down trip selection
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.

9ccb940a1b list models: include current dive in selection signal
After sending a selection-change signal, there follows a current
dive changed signal. Combine these two into a single signal, since
usually the current dive is changed when the selection is changed.

996f85771a selection: remove select_dive() and deselect_dive() functions
These were not optimal, because they would recalculate the current
dive and divecomputers for every invocation.

487974ea91 selection: avoid select_dive() and deselect_dive calls in dive list
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.

6df1c62dfc filter: set dive selection at once
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.

9f455b1457 selection: move current dive and divecomputer to selection.cpp
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.

9c253ee6c5 core: introduce divelog structure
The parser API was very annoying, as a number of tables
to-be-filled were passed in as pointers. The goal of this
commit is to collect all these tables in a single struct.
This should make it (more or less) clear what is actually
written into the divelog files.

Moreover, it should now be rather easy to search for
instances, where the global logfile is accessed (and it
turns out that there are many!).

The divelog struct does not contain the tables as substructs,
but only collects pointers. The idea is that the "divelog.h"
file can be included without all the other files describing
the numerous tables.

To make it easier to use from C++ parts of the code, the
struct implements a constructor and a destructor. Sadly,
we can't use smart pointers, since the pointers are accessed
from C code. Therfore the constructor and destructor are
quite complex.

The whole commit is large, but was mostly an automatic
conversion.

One oddity of note: the divelog structure also contains
the "autogroup" flag, since that is saved in the divelog.
This actually fixes a bug: Before, when importing dives
from a different log, the autogroup flag was overwritten.
This was probably not intended and does not happen anymore.

f42dee8ac2 selection: when changing current dive make sure it is selected
When an undo command selected invisible dives, a current dive outside
of the list of selected dives was chosen. This could have the very
unfortunate effect that the current dive was set, though not selected.
From an UI point of view this meant that the dive was displayed, but
edits would not be registered.

Change the setClosestCurrentDive function to select the current dive.

769915f3fe selection: create global single_selected_trip() function
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.

09b7fcbcf4 selection: add selection flag for trips
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.

7387b10b29 cleanup: remove current_dive parameter from divesSelected signal
The diveListNotifier.divesSelected() signal is used to inform the
models of a selection change. It sent the current dive as a second
parameter. This is redundant, because the only sender of the signal
sets current_dive just before sending the signal. Remove the
parameter, which appears to be an artifact.

f4f9ba9263 Selection: provide convenience function for single-dive selection
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.

755f185cfc Selection: move selection of "first" dive to core
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.

7787bfbf9e Selection: move commands/command_private.* to core/selection.*
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.
