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.

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

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

item changed place.
Also, emit dataChanged only on the actually changed element,

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

Since all other callers do not use callbacks, unslotify
"addStop()". The slot was the only user of the default parameters,

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.

On desktop, we have two CylindersModel concurrently: One in the

that flag to decide how to act.

When the show_unused_cylinders flag is not set, the cylinder tables
in the equipment tab and the planner should not show unused cylinders.
However, the code in CylindersModel is fundamentally broken if the
unused cylinders are not at the end of the list: The correct number
of cylinders is shown, but not the correct cylinders.
Therefore, add a higher-level CylindersModelFiltered model on top
of CylindersModel that does the actual filtering. Some calls are
routed through to the base model (notably those that take indexes,
as these have to be mapped), for some calls the caller has to get
access to the source model first. We might want to adjust this.
For filtering, reuse the already existing show_cylinder function
and export it via CylindersModel.

Instead of accessing the cylinder table directly, use the get_cylinder()

the function does bound checking. This is crucial for now as the code
hasn't be properly audited since the change to arbitrarily sized
cylinder tables. Accesses of invalid cylinder indexes may lead to
silent data-corruption that is sometimes not even noticed by

Instead of using fixed size arrays, use a new cylinder_table structure.
The code copies the weightsystem code, but is significantly more complex
because cylinders are such an integral part of the core.
Two functions to access the cylinders were added:
get_cylinder() and get_or_create_cylinder()
The former does a simple array access and supposes that the cylinder
exists. The latter is used by the parser(s) and if a cylinder with
the given id does not exist, cylinders up to that id are generated.
One point will make C programmers cringe: the cylinder structure is
passed by value. This is due to the way the table-macros work. A
refactoring of the table macros is planned. It has to be noted that
the size of a cylinder_t is 64 bytes, i.e. 8 long words on a 64-bit
architecture, so passing on the stack is probably not even significantly
slower than passing as reference.

The fill_default_cylinder() function calculated the MOD based
on the currently displayed dive. This does not seem to make sense:
- When importing dives, why would we care about the altitude and
salinity of the currently displayed dive, possibly from a different
trip.
- The planner is supposed to be thread-safe and should not touch
global variables.
Of course this means that the importing-functions have to fill
out altitude and salinity before creating the default cylinder,
but this is their problem. For a freshly created dive they will
get the default values, which still seems less random than the
values from the displayed dive.
