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.

Don't delesect dives, when unregistering them from the backend.
If a previously selected dive is added, select it in the dive-list.
For this purpose introduce a SELECTED_ROLE to query the DiveTripModel
for selected dives.
Unfortunately, when adding multiple selected dives, current_dive_changed
is called for each of them, making this very slow. This will have
to be fixed in subsequent commits.

Previously, each dive-list modifying function would lead to a
full model reset. Instead, implement proper Qt-model semantics
using beginInsertRows()/endInsertRows(), beginRemoveRows()/
endRemoveRows(), dataChange().
To do so, a DiveListNotifer singleton is generatated, which
broadcasts all changes to the dive-list. Signals are sent by
the commands and received by the DiveTripModel. Signals are
batched by dive-trip. This seems to be an adequate compromise
for the two kinds of list-views (tree and list). In the common
usecase mostly dives of a single trip are affected.
Thus, batching of dives is performed in two positions:
- At command-level to batch by trip
- In DiveTripModel to feed batches of contiguous elements
to Qt's begin*/end*-functions.
This is conceptually simple, but rather complex code. To avoid
repetition of complex loops, the batching is implemented in
templated-functions, which are passed lambda-functions, which
are called for each batch.

This refactors the undo-commands (which are now only "commands").
- Move everything in namespace Command. This allows shortening of
names without polluting the global namespace. Moreover, the prefix
Command:: will immediately signal that the undo-machinery is
invoked. This is more terse than UndoCommands::instance()->...
- Remove the Undo in front of the class-names. Creating an "UndoX"
object to do "X" is paradoxical.
- Create a base class for all commands that defines the Qt-translation
functions. Thus all translations end up in the "Command" context.
- Add a workToBeDone() function, which signals whether this should be
added to the UndoStack. Thus the caller doesn't have to check itself
whether this any work will be done. Note: Qt5.9 introduces "setObsolete"
which does the same.
- Split into public and internal header files. In the public header
file only export the function calls, thus hiding all implementation
details from the caller.
- Split in different translation units: One for the stubs, one for
the base classes and one for groups of commands. Currently, there
is only one class of commands: divelist-commands.
- Move the undoStack from the MainWindow class into commands_base.cpp.
If we want to implement MDI, this can easily be moved into an
appropriate Document class.

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].

For this, an output-parameter was added to the backend merge_dives()
function. When non-zero, instead of adding the merged dive to
the preferred trip, the preferred trip is returned to the caller.
Since the new UndoObject, just like the delete-dives UndoObject,
needs to remove/readd a set of dives, the corresponding functionality
was split-off in a helper function.
Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
For this, the core functionality of the split_dive() and
split_dive_at_time() functions were split out into new
split_dive_dont_insert() and split_dive_at_time_dont_insert(),
which do not add the new dives to the log. Thus, the undo-command
can take ownership of these dives, without having to remove them
first.
The split-dive functionality is temporarily made desktop-only
until mobile also supports "UndoObjects".

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).

In the UI it is possible to remove a dive from a trip twice,
which leads to a crash, because trip is NULL (obviously).

Currently it is possible to hide all columns by unchecking them
in the context menu that appears by right clicking the header
of the divelist. But once all are hidden the header disappears.
This can cause a situation where the user cannot show any
columns and the only fix for that is to edit the application
configuration.
To avoid this sutuation prevent the last column from being hidden.

The function DiveListView::fixMessyQtModelBehaviour() was used to
expand the first columns of dive-trips in the dive-list view.
This function was called everytime that the dive-list was modified.
It is kind of ludicrous that external callers would have to
tell the DiveListView, when it has to update its column headers.
Instead, place this functionality in the overriden reset() and
rowsInserted() functions, as these are the only ways that
rows can be added. Change the DiveTripModel to use the proper
beginResetModel()/endResetModel() pair instead of the previous
full deletion and full repopulation using the beginRemoveRows()/
endRemoveRows() and beginInsertRows()/endInsertRows().

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.

The column-widths must only be set once the source-model is that.
The old code realized this with a rather complicated logic.
Instead, simply set the source-model in the constructor and
set the column widths after that. Rename the corresponding
function from "setupUi" to "setColumnWidths".
Moreover, the setupUi function had different code-paths for
the first and other calls. Since it is only called once,
remove the other code paths.

Conceptually, the width of the columns should probably reside in
the view not the model. But much more severly, the old code didn't
work: Columns were set in a DiveTripModel, which was deleted
right away.
Therefore, move the logic back to the DiveListView. Introduce
a QVector<int> of the initial column widths, so that they can be
erased from the setting if unchanged.

learnHash() was always called in conjunction with add_hash(). The
pattern was that a local filename and a hash were connected in
the hash-to-filename and the filename-to-hash maps. Then, the
original picture-filename or url were registered in the filename-to-hash
map.
This commit changes learnHash() to take three parameters (original-filename,
local-filename and hash) and do all of the above. The new code is
simpler because no dummy picture struct has to be generated in
DiveListView::loadImageFromURL().
The tests were extended to check for all hash<->filename associations.

See referenced issue number. It leads back to an ancient (3 year old)
commit 512c42e. Not sure this issue is introduced there, but that's not
relevant.
Key in reproducing this is the location where the context menu is
requested (using the right mouse button). When it is the row next
to the trip, the add-to-trip succeeds correctly, otherwise
it is a no-op.
The solution is rather trivial (in hindsight). Just loop over the
selected dives, and try to find the trip we want to add to.
