When showing the "empty-state", the profile toolbar was
disabled. This was done via a "reverse" signal from the
profile to the MainWindow. Instead control the toolbar
in the MainWindow directly. Break out the plot-dive
functionality into a member function and there test
whether a dive is shown or not.
The signal makes no sense in the context of mobile
or printing.

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.

The ItemPos structure describes the position of various chart
elements on the scene. It had two problems:
- The identifiers were starting with an underscore followed
by a capital letter. This is reserved to the compiler.
- The global object was initialized in the ProfileWidget's
constructor. This means that if there are multiple
ProfileWidgets, the structure is reinitialized even though
it is constant.
Remove the underscores (what was the point anyway?) and
initialize the structure in its own constructor. Moreover,
make the object const to drive the point home.
If this ever needs to be variable, each ProfileWidget
should get its own copy of the object.

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.

When moving the handle with the mouse, the old code tried
to be smart about changing the active handle when crossing
handles.
To me this always felt weird and it was inconsistent with
mouse-move. Theregore, simply do nothing special at all. The
user should hopefully get an intiutive grasp of what's going
on when moving one handler across another.

This model is only needed when in plan mode. To enable multiple
profilewidgets at the same time (e.g. for the mobile app or
for printing), make the pointer to DivePlannerPointsModel a
member variable that is initialized at construction time.
Moreover, allow passing null as the DivePlannerPointsModel,
in which case planning will be disabled. This will be useful
for simple printing.

The ProfileWidget2 slots, which reacted to model changes were
broken. They did not add / remove items at the changed positions,
but arbitrarily at the end. Moreover, they assumed that only
a single item was added / removed and thus violated the model/view
API.
This worked because the handles are completely reset after each
operation and the model only ever touched single items.
Nevertheless, this has to be fixed if we ever want finer grained
undo.

This now actually displays the calculated ceiling in the profile. There is
still an issue where if the user toggles the setting the already cached profiles
aren't recalculated - that's part of a bigger profile cleanup effort.
Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
The code tried to only replot the profile if necessary, notably
when in edit mode or the ceilings are shown.
That seems like pointless premature optimization, which only
complicates things: The profile is replot every time a
"dive handle" is moved, which means that we depend on the
replotting being reasonably fast. Why should it then not
be redrawn if the settings change?
Let's remove this, as it makes control flow easier to reason
about.
This makes the isPlotZoomed member variable redundant. Remove it.

Recently (674c20227b), the call to ProfileWidget::clearHandlers()
was moved from PlannerWidgets::replanDive() to ProfileWidget2.
This cause a crash, because the code assumes that the number
of elements in the handles-vector the divepointplanner model
is the same.
Clearing the handles violates this assumption. It turns out
that the clearHandlers() function is broken anyway: it clear
the handles-vector, but not the gases-vector, which should
likewise have the same number of elements. It appears that
the clearHandlers() function is an artifact and it is
mysterious how this has worked so far. Remove.

On clicking the DivePictureItem "trash" icon, the item would delete
the picture it represents in the currently displayed dive. This needed
an access to the global "displayed_dive" variable, which we want
to get rid of to make the profile more flexible. For example, we
want to render the profile for printing without messing with global
state.
One solution would be to save the dive with every DivePictureItem.
This commit follows a more Qt-ish strategy by handling this via
signals: The close button emits a signal that is recast by the
DivePictureItem and ultimately handled by the ProfileWidget2,
which knows which dive it represents.

This function, which removes the handlers from the profile, was called
in setAddState() but not in setPlanState(). In the latter case it was
called explicitly by the caller.
Move the call from the caller into the function. This allows us to

ProfileWidget2::plotDive() had this weird interface, where passing
in NULL as dive would mean "show current_dive". However, most callers
would already pass in current_dive. Therefore, unify and always pass
in current_dive if the caller wants to draw the current dive.
This allows us to interpret NULL as "show empty profile". Thus,
passing in current_dive when there is no current_dive simply shows
an empty profile. This makes the calling code in
MainWindow::selectionChanged() simpler.

Firstly, the parameter appears conceptually wrong, as replot suggests
that the currently shown dive is replot. Secondly, the only caller that
passed a parameter was passing in current_dive, which is just what happens
if one doesn't pass a parameter. Therefore, change that caller (call
plotDive directly) and remove the parameter.

Add a DiveListNotifer::eventsChanged signal, which is emitted when

The removeEvent(), hideEvents() and editName() actions need
the DiveEventItem they are applied to. This was transported
via QAction's user-data, which means casting to void and
back.
By using lambdas instead, this can be made perfectly type-safe:
First we are 100% sure that we have a DiveEventItem because
we check the result of a dynamic_cast<>. Then we can pass
it to the even using its proper type.

When adding a gas change event via a context menu, the gas-id and
timestamp were passed in two distinct ways.
1) The gas id was extracted from the text of the action. This meant
doing rather complicated parsing.
2) The timestamp was passed via the "user data" of the action, which
means transporting via "QVariant".
There is a much simpler way to pass arbitrary data, that is strongly
typed: lambdas. Instead of shoehorning the data onto the action in
an archaic way, we can simply connect to a stateful lambda. That's
what they're for after all.

The ProfileWidget2::recalcCeiling() function is used in one place,
namely when an undo-command changes the mode. It recalculates
decompression data and repaints the ceilings and thus avoids a
full profile-redraw.
This is smart, but it becomes problematic when the dive is changed
and the ceiling is recalculated before the profile is redrawn.
The DivePlotDataModel then still has data from the previous dive
but cylinders of the new dive are accessed.
This kind of situation may arise if multiple dive fields are
updated, as for example when replanning a dive.
Currently, this only causes a temporary mis-calculation. When
removing MAX_CYLINDERS this will lead to crashes.
One might attempt to fix the whole data-dependency mess. This
commit goes the cheap route and simply redraws the profile when
the mode is changed. Yes, it is in a way ineffective, but we
do worse things. The ProfileWidget2::recalcCeiling() thus becomes
unused and is removed.

Allow splitting out a dive computer into a distinct dive. This
is realized by generating a base class from SplitDive.
This turned out to be more cumbersome than expected: we don't
know a-priori which of the split dives will come first. Since
the undo-command saves the indices where the dives will be insert,
these have to be calculated. This is an premature optimization,
which makes more pain than necessary. Let's remove it and
simply determine the insertion index when executing the command.
