64a1a50e10 Dive list: remove sortColumn and currentOrder members
Since the QHeaderView of DiveListView is now the authority
over sort-column and sort-order, it makes little sense
to keep these as member variables. That would only risk
inconsistencies. Remove them and query the QHeaderView
instead.

We still need to keep track of currentLayout, as we
have to detect if it changes to change the underlying
model from tree to list or vice-versa.

f2f18b4e16 Dive list: split reload() in reload() and setSortOrder()
The DiveListView code had a very fundamental problem with its
header: Each had its own idea of who is responsible for sorting.
Since we can't easily change QHeaderView, accept QHeaderView
as the authority on sort-column and order.

To make this possible, split the reload() function in two
distinct functions:
 - reload() reloads the model and sorts according to the
   current sort criterion.
 - setSortOrder() tells the header to display a certain
   sort criterion. If this is a new criterion, it will then
   emit a signal. In this signal, resort according to that
   criterion.

Thus, the actual sorting code has to be moved from the
headerClicked() to a new sortIndicatorChanged() slot.
Morover, the sorting of the QHeaderView has to be used.

6fb3a499e6 Dive list: remove forceSort parameter from DiveListView::reload()
DiveListView::reload() was called for full reset of the dive list
and for changing the view (tree vs. lis) in DiveListView::headerClicked().
Since the latter does sorting by itself, a parameter "forceSort" was
introduced, which defaulted to true, but was set to false by
DiveListView::headerClicked().

To remove complexity, simply let DiveListView::headerClicked() set
the view by itself and remove tha parameter.

9829e49815 Dive list: move dive-selection code from filter to list
After invalidating the filter, the dive-selection was modified to
ensure that at least one dive is selected. This was done in the
filter code, but it seems preferrable to do this in the dive-list
code, which has direct access to the selection-model.

Therefore, move the code from MultiFilterSortModel to DiveListView.
While doing so, split the code in DiveListView into more functions to:
1) Get the index of the first dive (if any).
2) Select the first dive (if any).

This allows a distinct size reduction of conditional compilation
in MultiFilterSortModel (accesses to MainWindow are not possible
in mobile code).

3c6cdfd8c0 Dive list: propagate current-item to frontend
The command-objects select a current item, but this selection
was not propagated to the front-end. The current item is the
base for keyboard-navigation through the dive-list and therefore
should be set correctly.

It took some experimentation to get the flags right:
 QItemSelectionModel::Current
Hopefully, these are the correct flags across all supported
Qt versions!

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.

23db0ba68d Dive list view: replace signal-magic by flag
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.

89e0c3f464 Cleanup: make DiveTripModel a global object
DiveTripModel (the model describing the dive-list) was destroyed
and recreated on every reset of the list. This seems excessive.

1c4a859c8d Cleanup: remove all override modifiers
Commit df156a56c0 replaced "virtual"
by "override" where appropriate. Unfortunately, this had the
unintended consequence of producing numerous clang warnings. If
clang finds a override-modified function in a class definition,
it warns for *all* overriden virtual functions without the override
modifier.

To solve this, go the easy route and remove all overrides. At least
it is consistent.

4bdd811f06 Cleanup: remove DiveListView::fixMessyQtModelBehaviour()
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().

5e1e6110ce Cleanup: remove parameter from currentDiveChanged signal
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.

67a875ef81 Dive list view: setup columns in constructor
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.

079b99135a Dive list view: move column width logic back from DiveTripModel
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.

4e8079f527 Cleanup: make lastUsedDir() functions static and non-slot, respectively
The lastUsedDir() functions of MainWindow and Smrtk2ssrfcWindow don't
use any member-objects and are only used in their respective translation
units. Therefore, remove them from the class and made of static linkage.

The lastUsedImageDir() function was declared as a slog, which makes
no sense. Make it a normal static function (though one might argue
why it is assiociated with the DiveListView class in the first place).

e3118d915c divelist: prevent a crash for missing column width
The `static int defaultWidth[]` definition in divelistview.cpp
could potentially end up missing an element which can later result
in out-of-bounds access when iterating through the list of
columns and updating their widths.

Add a couple of methods in DiveTripModel for setting and getting
the widths and use those. The default values are now pre-set in a
QVector in the DiveTripModel() constructor.

Throw warnings if out-of-bounds columns are requested.

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.

Also, move the graphicsview-common.h/cpp to subsurface-core because

desktop and mobile versions
