c263487e7c cleanup: remove MainWindow::setFileClean()
This function was used to unify both methods of tracking unsaved
changes. Since desktop now only uses the undo system, it can
be replaced by a single call to "Command::setClean()".

Arguably, the UI is the wrong place to do this and the appropriate
calls should be done by the core. However, let's play it safe
for now and avoid any breaking change.

4f5621c4c6 Planner: fold MainWindow::setupForAddAndPlan into createSimpleDive()
There was only one caller of MainWindow::setupForAddAndPlan() left

Thus, we might just as fold the former in the latter and thus

Split out the actual filtering from the MultiFilterSortModel.
Create a DiveFilter class that does the actual filtering.
Currently, mobile and desktop have their own version of this

The idea here is that the trip-model and undo-commands have

05200f9266 Cleanup: unify idiosyncratic singletons
The way we handle singletons in QML, QML insists on allocating the
objects. This leads to a very idiosyncratic way of handling
singletons: The global instance pointer is set in the constructor.

Unify all these by implementing a "SillySingleton" template. All
of the weird singleton-classes can derive from this template and
don't have to bother with reimplementing the instance() function
with all the safety-checks, etc.

This serves firstly as documentation but also improves debugging
as we will now see wanted and unwanted creation and destruction
of these weird singletons.

75767c456a Turn application state into enum
The application state was encoded in a QByteArray. Thus, there was
no compile-time checking. Typos would lead to silent failures.

Turn the application state into an enum. Use the enum-class construct,
so that the values don't polute the global namespace. Moreover,
this makes them strongly typed, i.e. they don't auto-convert to
integers.

A disadvantage is that the enums now have to be cast to int
explicitly when used to index an array.

Replace two hash-maps in MainWindow to arrays of fixed sizes.

Move the application-state details into their own files.

88ed5bf050 Desktop: destroy maintab before destructing mainwindow
Apparently, in some Qt-versions the destructor of the base class
calls hide on child-objects (according to Qt's object hierarchy).
This is obviously called after the derived class has been destructed.

In a concrete case, the base class of the destructed MainWindow
would hide the TabDiveSite object. That would reset the filtering
if a dive site was selected, which would indirectly access the
MainWindow, which is already partially destroyed.

Therefore, destroy the MainTab before destroying the MainWindow.
Do this by keeping it as a std::unique_ptr subobject. Thus, it
will be destroyed before the MainWindow and remove itself from
Qt's object hierarchy.

ed09e6a909 Desktop: Make filterWidget2 a subobject of MainWindow
In commit b0556abdd35f96b816ba11e40bf5707abe0c3ebf, the filter-widget
and the filter were connected by a direct function call. This led
to a rather obscure crash on application-close with Qt 5.12. The
crash is due to the Ui::MainWindow class being a sub-object of MainWindow,
but the FilterWidget2 being *not* a subobject.

What happens is that after calling the MainWindow destructor, the
subobjects are destructed, notably the Ui class. Then the base-class
destructor is called (which makes sense, as destructors are called
in reverse order of constructors).

But: the QObject destructor calls hide() on all still existing child-objects
according to Qt's object hierarchy, notably the visible FilterWidget2.

Now the FilterWidget2, on hiding, updates the MainWindow, which has already
destructed all its subobjects. Crash.

Prevent this crash by making FilterWidget2 a subobject of MainWindow
and thus have it destructed before running the QObject destructor.

Alternative ways would be:
1) Use signal/slot() instead of function calls, as these are automatically
   removed if an object is destroyed.
2) Make the FilterWidget2 subobject a smart-pointer. Thus, we probably
   wouldn't have to include the corresponding header.
3) Make the FilterWidget2 subobject a plain pointer and delete it
   explicitly in the constructor.

78e2560296 Cleanup: Turn widget accessor-functions into simple pointers
The keeps track of different sub widgets needed by other parts
of the code, notably:
	MainTab
	PlannerDetails
	PlannerSettingsWidget
	ProfileWidget2
	DivePlannerWidget
	DiveListView
Access to these widgets was provided with accessor functions.
Now these functions were very weird: instead of simply returning
pointers that were stored in the class, they accessed a data
structure which describes the different application states.
But this data structure was "duck-typed", so there was an
implicit agreement at which position the pointers to the
widgets were put inside. The widgets were then down-cast by
the accessor functions. This might make sense if the individual
widgets could for some reason be replaced by other widgets
[dynamic plugins?], but even then it would be strange, as one
would expect to get a pointer to some base class.

Therefore, directly store the properly typed pointers to the
widgets and simply remove the accessor functions. Why bother?

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.

43c3885249 Undo: isolate undo-commands
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.

df156a56c0 Cleanup: replace virtual by override where appropriate
The keyword "virtual" signalizes that the function is virtual,

It is not necessary to repeat the "virtual" keyword in derived

"override" should be used instead. It results in a hard compile-
error, if no function is overridden, thus avoiding subtle bugs.

Replace "virtual" by "override" where appropriate. Moreover,
replace Q_DECL_OVERRIDE by override, since we require reasonably

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.

cfd4c42829 Profile heatmap/heartrate: Only enable max one of these at same time
Only allow to enable maximum one of both items tissue heatmap or
heartrate in profile.
This is done by always switching off the other one at the moment you
turn on one of the two items (heatmap or heartrate).

a25f54e3c2 Use queued connection to thread-safe MainWindow error handling
Up to now, errors produced by threads were not directly shown in
the MainWindow. Code running in the GUI thread had to manually
show the errors.

This can be simplified by using Qt's queued connection as message
passing facility.
