This makes sure that the dive plan is updated (including the
planner notes) when parameters of the dive or the planner
change.
This fixes a bug reported by Jay Anchor.
There is a chance that by partly undoing 77a6bc6d62, this
introduces too many recalculations of the plan. But without
this patch, there are definitely not enough recalculations.

There are two cases in this function: with and without holding
the control-key. The former deletes one point, the latter all
points starting with the selected point to the end.
The code was interlaced making it very hard to reason about.
Notably, it was buggy: with control, all points could be
deleted, leading to a crash.
Split the function in two versions, with their own bound
checking. This produces a bit of duplicate code, which
might be broken out later.

When updating the dive profile, a thread is started to calculate
plan-variations. This is done even when only editing the profile
or when variation calculation is disabled by the user. The thread
then exits if it shouldn't calculate the variations.
Turn this around: test whether variations should be calculated
before starting the thread.

Split the function in one external version, that updates the
dive profile and cylinders and one internal version, that
does no recalculations. In the latter case, the caller is
responsible for updating the dive.
Thus, the recalculation flag-clearing can be removed from
removeDeco().

In planner or profile-edit mode, the plotDive() function takes
the current plan and turns it into a dive profile. Not only
is this a layering violation (the display layer modifying the
dive), it is also fundamentally flawed. The control-flow is
out of control, if you wish. There are numerous reasons why
the profile needs to be replot, many of which do not need
a recalculated dive profile.
Move the code that updates the dive-profile to the
DivePlannerPointsModel. Thus, the profile recalculations
and replots can be pooled. This will break the planner, since
there now might be missing calls to the profile recalculation.
But it already has some positive effects: when removing
multiple points, the profile is only recalculated once.
This will need much more work, but it is a start.

The DivePlannerPointsModel::addStop() function is called by
the profile to add a planner-stop. It is also used internally
to create profiles.
If we ever want to include this in the undo system, we have
to split these into to versions. One will ultimately place
an undo command and update the profile, the other one doesn't.
For now, this makes the external interface simpler, as some
parameters are redundant.

The DivePlannerPointsModel::createTemporaryPlan() function had
two distinct and independent parts:
1) create the data points.
2) create the dive sample and calculate variations.
The second part was only exectuted if the recalc flag was set.
Out of the two callers, one was explicitly disabling and setting
the recalc flag to avoid the second part.
The much more logical thing is to simply split the function in
two and only call the first part.
To avoid any functional change, the second caller (the profile)
still tests for the recalc flag. However, if it shouldn't replot
a new plan, why calculate it in the first place!? And why does
the display function change the plan at all? This appears all
very ill-thought out and should be changed in due course.

The only external user of setRecalc() was turning recalculation
on. In fact, this happened when constructing the planner-widget.
However, for example editing of the profile only works when
the recalc flag is on.
This is all very confusing, let's just turn the flag on by
default and remove the accessor. Internally, the planner can
simply use the std::exchange function to set and reset the
recalc flag.
Perhaps the setting/resetting can be replaced by simple
recalc = true;
...
recalc = false;
pairs. It is unclear whether there is need for recursion.
Something to be investigated.

So far the profile operated on the global displayed_dive. Instead,
take the dive to be displayed as a parameter to the plotDive()
functions.
This is necessary if we want to have multiple concurrent
profile objects. Think for example for printing or for mobile
where multiple dive objects are active at the same time.

To remove global state, make the dive that DivePlannerModel
works on a member variable. Pass the dive in createSimpleDive()
and loadFromDive(). Moreover, this should pave the way to more
fine-grained undo in the planner. Ultimately, the planner
should not be modal.
Attention: for now, the dive must still be displayed_dive,
because of the convoluted way in which the profile and the
planner work on the same dive.

Both loadFromDive() callers were clearing the model before
calling loadFromDive(). Move the clearing into that function

Apparently this changes the way that no-cylinder dives are

There must not be two dive planner points at the same time
stamp, as this violates the laws of physics (and internal
assumptions).
The corresponding test was done in the profile code at
two different places with floating point arithmetics.
This is a bad idea, because
1) code duplication
2) danger of rounding issues
Instead, do this in one central point in the planner model
and use integer arithmetics. Simply add a few seconds until
a unique timestamp is obtained.

When reordering the points, the DivePlannerPointsModel would
not emit the appropriate move signals, but simply a data-changed
signal over all elements. This obviously violates Qt's
model/view API, though it is probably harmless. Let's do
the right thing so that the frontend knows that the selected
item changed place.
Also, emit dataChanged only on the actually changed element,
not all elements.

When clicking on "+" in the planner, a default stop point was
added using a signal/slot connection. This used the archaic
string-based connect syntax, because it was realized with
default parameters passed to "addStop()". Instead, add a
"addDefaultStop()" slot, which passes the default parameters.
Since all other callers do not use callbacks, unslotify
"addStop()". The slot was the only user of the default parameters,
so they can be removed alltogether.

The dive selection was initialized during data-reset. However,
this emitted a signal before all data-reset routines were run.
Ultimately, this led to access-after-free in the statistics code.
Instead, move the select_newest_visible_dive() signal from the
divelist-model to the process_loaded_dives() function. There
is no point in initializing the selection if the dive data
is cleared after all.
This change broke closing of the log, because the UI-selection
was not reset. Therefore, when clearing the data, clear the
selection before proceeding with clearing.

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.

Remove this in a step to make the profile reentrant.

The DiveCalculatedCeiling profile-item has a recalc()
function, which calls "dataModel->calculateDecompression()".
This is a questionable reversal of control-flow: The
profile-item should paint the model-data not change it.
The code was supposed to be called under two conditions:
1) The value of the calcceiling3m preferences flag changed.
This code was buggy for two reasons: Firstly, the cached
value was always initialized to false, which means that
sometimes the first call was missed. Secondly, the
settingsChanged() functions was only called when closing
the preferences window, not when changing the flag in the
profile widgets.
2) The datetime of the dive changed. The whole control-flow is
pretty absurd (due to "bit rot"):
- The replan-dive command sends a date-time changed signal.
- The main tab changes the date-time and informs the profile.
- The profile sends a signal to the item.
- The item instructs the model to recalculate the
decompression.
- The model causes the profile to be redrawn.
In any case, the whole thing is moot, because the decompression
is recalculated for *every* profile plot in create_plot_info_new().
Let's remove the code from the DiveCalculatedCeiling profile-item
and the calculateDecompression() function, which is now not
used anymore.
