7067e33596 Undo: select dives after add, remove, merge, split dive commands
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.

63b65a7e20 Undo: implement autogrouping of trips in DiveAdd
If the autogroup flag is set, search for appropriate trips in
DiveAdd() and add the dive to this trip. If no trip exists, add
a new trip.

f427226b3b Undo: make diverse trip-related operations undo-able
AddDivesToTrip, CreateTrip, AutogroupDives, RemoveAutogenTrips
and MergeTrips basically all did the same thing as RemoveDivesFromTrip,
which was already implemented. Thus, factor our the common functionality
and hook it up to make all these functions undo-able.

Don't do the autogroup-call everytime the dive-list is rebuilt
(that would create innumberable undo-actions), but only on dive-load /
import or if expressly asked by the user [by switching the autogroup
flag].

12df9faaa2 Undo: implement undo of manual dive-creation
Play manual addition of dives via an UndoCommand. Since this does in
large parts the same thing as undo/redo of dive deletion (just the
other way round and only a single instead of multiple dive), factor
out the functions that add/delete dives and take care of trips.

The UI-interaction is just mindless copy&paste and will have to
be adapted.

403dd5a891 Undo: fix multi-level undo of delete-dive and remove-dive-from-trip
The original undo-code was fundamentally broken. Not only did it leak
resources (copied trips were never freed), it also kept references
to trips or dives that could be changed by other commands. Thus,
anything more than a single undo could lead to crashes.

Two ways of fixing this were considered
1) Don't store pointers, but unique dive-ids and trip-ids.
   Whereas such unique ids exist for dives, they would have to be
   implemented for trips.
2) Don't free objects in the backend.
   Instead, take ownership of deleted objects in the undo-object.
   Thus, all references in previous undo-objects are guaranteed to
   still exist (unless the objects are deleted elsewhere).

After some contemplation, the second method was chosen, because
it is significantly less intrusive. While touching the undo-objects,
clearly separate backend from ui-code, such that they can ultimately
be reused for mobile.

Note that if other parts of the code delete dives, crashes can still
be provoked. Notable examples are split/merge dives. These will have
to be fixed later. Nevertheless, the new code is a significant
improvement over the old state.

While touching the code, implement proper translation string based
on Qt's plural-feature (using %n).

6dc1dcaea5 Import: pass "downloaded" parameter to process_imported_dives()
process_imported_dives() is more efficient for downloaded than for
imported (from a file) dives, because it checks only the divecomputer
of the first dive.

This condition is checked via the "downloaded" flag of the first
dive. Instead, pass an argument to process_imported_dives().

810903bdb9 Import: pass a dive table to process_imported_dives()
Dives were directly imported into the global dive table and then
merged in process_imported_dives(). Make this interface more flexible,
by passing an independent dive table.

The dive table of the to-be-imported dives will be sorted and merged.
Then each dive is inserted in a one-by-one manner to into the global
dive table.

This actually introduces (at least) two functional changes:
1) If a new dive spans two old dives, it will only be merged to the
   first dive. But this seems like a pathological case, which is of
   dubious value anyway.
2) Dives unrelated to the import will not be merged. The old code
   would happily merge dives that were not even close to the
   newly imported dives. A surprising behavior.

c32e71e64d Dive information: fix surface interval calculation
The old surface interval calculation had fundamental issues:

1) process_all_dives(), which calculates the statistics over *all*
   dives was used to get the pointer to the previous dive.
2) If two dives in the table had the same time, one of those would
   have been considered the "previous" dive.
3) If the dive, for which the surface interval is calculated is
   not yet in the table, no previous dive would be determined.

Fix all this by creating a get_surface_interval() function and
removing the "get previous dive" functionality of process_all_dives().
Remove the process_all_dives() call from TabDiveInformation::updateData().

35b8a4f404 Core: split process_dives() in post-import and post-load versions
process_dives() is used to post-process the dive table after loading
or importing. The first parameter states whether this was after
load or import.

Especially in the light of undo, load and import are fundamentally
different things. Notably, that latter should be undo-able, whereas
the former is not. Therefore, as a first step to make import undo-able,
split the function in two versions and remove the first parameter.

It turns out the the load-version is very light. It only sets the
DC nicknames and sorts the dive-table. There seems to be no reason
to merge dives.

find_trip_by_idx() and find_matching_trip() weren't used anywhere.
The trip index actually is only misused as a "trip saved"-flag.

8e21a65653 Localize global planner state
For UI responsiveness, we need to be able to run the planner in the background. This needs the
planner state to be localized (and we need to pass a pointer around).

In order to not let too many lines overrun (and to save typing in the future)
I have renamed instances of struct deco_state to ds. Yes this should have gone
to a separate commit but I accidentally commit --amend'ed it.

Computing of planner variations is temporarily disabled.

Unlock the planner when returning early

So we don't deadlock in add dive and recreational mode (which
use the planner without actually planning).

4158a4c7de init_deco correctly identify previous dives and report overlapping dives
When changing the date/time of a dive in the planner the dive may end
up in a totaly new position in respect to date/time of other dives in
dive list table. It can be moved to the past or the future before or after
other existing dives. It also could overlap with an existing dive.

This change enables identification of a new "virtual" dive list position
and based on this starts looking for previous dives.
Then it (as before the change) does init the deco calculation with any
applicable previous dive and surface interval.
If some of these applicable dives overlap it returns a neg. surface time
which is then used in the planner notes to prohibit display of results.

590af9ae7d Add helper to find the dive closest to a given time
If we want to keep the selected dive "close" to where it was before an
operation (whether a delete, or a reload, or something like that), then
the most intuitive thing to do appears to be to select either the same
dive again (if it still exists), or one very close to it in time. This
helper allows us to identify the dive in the current dive list that is
closest to the given time.

We do this in the C code to ensure that we look at all dives in the
dive_table - based on the id that is returned the UI can then figure out
where this dive is currently shown.

7be962bfc2 Move subsurface-core to core and qt-mobile to mobile-widgets
Having subsurface-core as a directory name really messes with
autocomplete and is obviously redundant. Simmilarly, qt-mobile caused an
autocomplete conflict and also was inconsistent with the desktop-widget
name for the directory containing the "other" UI.

And while cleaning up the resulting change in the path name for include
files, I decided to clean up those even more to make them consistent
overall.

This could have been handled in more commits, but since this requires a
make clean before the build, it seemed more sensible to do it all in one.
