Placing labels at half-integer values gives horrible

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.

When in planner mode, don't allow the user to change the application
state. This brought us nothing but troubles and inconsistencies.
Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
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.

When reparenting the statistics widget, QtQuick deletes
the rootNode and all the child nodes. It is unclear whether
this is a bug or intended behavior. In any case, it means
that the pointers to QSG nodes in the chart items become
stale.
To avoid this, delete all chart items in the root node's
destructor, before QtQuick can do anything. It is unclear
from which context this is called (render or UI) and whether
this is even valid. In some tests, it seemed to work.
The difficulty is that all the stale pointers to chart items
have to be deleted as well. All in all, the QSG memory
management is a big nuisance and very brittle.

Since we no longer show the noisy git updates to the user, it has become
harder for them to know whether a sync to the cloud was successful.
Since a manual sync will never show the new 'what did you change and
here's how you undo it' notification, it seems easy enough to simply
show a status update.
This adds a passive notification with no action button after the user
either uses the main menu or pulling down on the dive list in order to
trigger a manual sync.

The updatePaintNode() function, which is run on the render
thread detected a geometry change and initiated recalculation
of the chart layout.
This means that plotAreaChanged() was called in two different
thread contexts, which is questionable. Instead, hook into
the geometryChanged() function and recalculate the chart items
there.
This fixes a rendering bug, because the old code would first
delete unneeded items and then rerender the chart. Thus, old
grid and tick items were still visible.

The way the starting time of a new plan was set was bonkers:
1) PlannerWidgets::planDive() invokes DivePlannerPointsModel::
createSimpleDive().
2) createSimpleDive() calls DivePlannerPointsModel::
setupStartTime()
3) setupStartTime() emits a signal startTimeChanged()
4) startTimeChanged is caught by PlannerWidget and sets
the UI field
5) change of the UI field emits a timeChanged() signal which
is connected to DivePlannerPointsModel::setStartTime()
6) setStartTime() sets the time of the plan and displayed_dive
and emits dataChanged()
7) dataChanged() replots the dive()
8) Back in DivePlannerPointsModel::createSimpleDive() the diveplan
start time is overwritten with displayed_dive (the value are
equal owing to 6)
Wow!
But it gets worse:
9) The initial dive plan is set up in createSimpleDive().
Since the profile is drawn in 7) after clearing the displayed_dive
and before constructing the initial plan, the profile is shown
on a dive without samples. It therefore generates a dummy profile.
To make this somewhat less insane, remove the startTimeChanged()
signal in 3), explicitly set the start time of plan and dive to
the one calculated by setupStartTime() and explicitly set the UI
filed in the plannerWidget.
This still indirectly draws the profile via signals in a convoluted
way, but at it straightens out things somewhat. Most importantly,
the profile doesn't have to generate a fake DC.

The scatter plot items shared their textures. These were
std::unique_ptrs and cleaned up on exit. Owing to QSG's

terminated its threads led to crashes. Therefore, leak the

than a crash.

The code was wrong, because it deleted the ChartItems in the
main UI thread, not the render thread. This would delete the
QSG nodes in the UI thread and then crash on mobile.
Therefore refactor this part of the code by adding the
items to be deleted to a list that will be deleted by the
render thread.
As a drop in replacement of std::unique_ptr, implement
a silly ChartItemPtr class, which auto-initializes to null.
This turns the deterministic and easily controlled memory
management into a steaming pile of insanity. Obviously,
this can be made much more elegant, but this has to do for now.
