Unfortunately Coverity doesn't understand that most Qt data
structures are copy-on-write. It's a mis-feature of Qt, but
it is the way it is. Thus, passing by value is not an issue.
Out of ca. 25 warnings only two were legit. Let's silence
the others by either std::move()ing or passing by reference,
as would be idiomatic C++, which Qt is not.

The dive-site editing can be reached from two states: from the
dive view and the dive list view. It always jumped back to
the dive view.
Therefore, remember the state. Use a stack-like structure, so
that the feature can be used for the dive-site view as well.
This is a bit inconsistent, because for example the statistics
view does not remember the previous state and allows a direct
jump to a different state. That should be fixed at some point.

Currently, when the profile is in edit mode, the user can't
save, exit, plan a new dive and is requested to save the
current dive. However, this makes no sense anymore, since
the profile always switches to edit mode when showing a
manually added dive.
If the user has any unsaved profile changes, the usual
dirty checks of the undo-system apply.
Only show above behavior when in the planner. There it is
useful because, these are not included in the undo system.

Place undo commands for every change of the profile, not
only on "saving". Move the edit-mode from the mainwindow
and the maintab to the profile widget.
This is still very rough. For example, the only way to exit
the edit mode is changing the current dive.
The undo-commands are placed by the desktop-profile widget.
We might think about moving that down to the profile-view so
that this will be useable on mobile.

Create a new class that encapsulates the profile-widget UI.

When switching to the "plan" or "add" (which should rather be
called "edit", by the way) mode of the profile, the "shortcuts"
for copy&paste, undo&redo, etc. are disabled. When switching
to "profile" mode, they are reenabled.
This was done in a most convoluted way:
- The MainWindow calls the set*State() function of the profile.
- The Profile emits [disable|enable]Shortcuts() signals.
- The MainWindow catches these signals and does the enabling
or disabling.
Not only is this very hard to reason about, it is also in
contradiction to the profile being part of the display layer.
Moreover, in editCurrentDive() the MainWindow disabled the
shortcuts itself, so this was all redundant.
For the sake of sanity, let's just move this logic to the
MainWindow, unslotify the [disable|enable]Shortcuts() functions
and make them private.

also has its application state, but that is something completely
different.
The last remaining user of the application state was to flag

The memory management of the quadrant widgets is a total mess:
When setting the widget, the QSplitters take ownership, which
means that they will delete the widget in their destructor.
This is inherently incompatible with singletons, which must
not be deleted.
To avoid all these troubles, remove the widgets from the
QSplitters in the desctructor of the MainWindow. This of
course means that we now have to take care about deletion
of the widgets.
For local widgets use std::unique_ptr, for singletons use
a static variable that is deleted on application exit.
Sadly, for the map widget we can't use a normal singleton,
because the QML MapWidget's memory management is buggy.
Add a comment in the source code explaining this.

There was the "application state", which decided what to show
in the "quadrants" and the "view state" which decided which
quadrant to show. These interacted in a hard-to-grasp way.
The "view state" is used to show the map or dive list in
full screen.
I simply couldn't get these two orthogonal states to interact
properly. Moreover the thing was buggy: If a quadrant was hidden,
the user could still show it, by dragging from the side of the
window, at least under KDE.
To solve these woes, merge the two states into a single
application state. If the widget of a quadrant is set to null,
don't show it. So the four "view states" are now "application
states" where three of the four quadrants are not shown.
This also changes the memory management of the widgets:
widgets that are not shown are now removed from the QSplitter
objects. This makes it possible that the same widget is
shown in *different* quadrants.
While writing this, I stumbled upon a Qt bug, which is known
since 2014:
https://forum.qt.io/topic/43176/qsplitter-sizes-return-0
When restoring the quadrant sizes there was a test whether
the quadrant size is 0. If that was the case, a default size
was set. This seems not to work if the widgets were recently
added. Since this test now always fails, make the quadrants
non-collapsible and thus guarantee that 0 is never saved as
a size.

Add a new "statistics" application state. In the statistics state
show the statistics widget and the filter in the top quadrants.
The idea is to allow filtering and doing statistics at the same
time.
Sadly, we can't use the filter-widget in different quadrants,
because Qt's ownership model is completely broken / inflexible.
It does not support a widget having different parents and
thus a widget can only belong to one QStackedWidget.
Hiding the map in the statistics view is quite hacky:
Since the view of the quadrants is not determined by the
"ApplicationState", we have to restore the original quadrant
visibility when exiting the stats mode. Therefore, set the
original visibility-state when changing application state.
The MainWindow-quadrant code really needs to be rewritten!

Around 2015 there was a push to move planner UI code from
mainwindow.cpp to diveplanner.cpp. That never was completed,
presumably because the planner is actually three widgets.
Collect these widgets in one PlannerWidgets class and move
the code there.
This is not a full dis-entanglement, as the plannerwidgets
have to access the profile via the mainwindow. But at least
it collects the planner UI code at a single place.

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.

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.

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.

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.
