Now that we have defined addition and subtraction on unit
classes, let's use them in a few examples.
Yes, some of these are a bit pointless, because they are
of the kind
a.mbar - b.mbar => (a-b).mbar
However, these probably should be further simplified
by storing the result in a unit type.
This commit is mostly a proof-of-concept.

The goal here is to add general addition and scalar multiplication
functions to the unit types.
Thereto, we need a CRTP
(https://en.wikipedia.org/wiki/Curiously_recurring_template_pattern)
base class.
However, this breaks compound initialization, so we have to use
named initializers:
weight_t { 2000 } -> weight_t { .grams = 2000 }
The good thing is that this is exactly how these classes were
supposed to be used: make the unit explicit!

Allow the initial gas of the dive to be edited through the context menu
in the dive profile, by right-clicking into the profile at the very
start of the dive.
Of course this will likely completely invalidate the decompression
calculation of any actually logged dives, but this is no different to
the addition and modification of gas changes during the dive that is
already possible.

Improve the event loop architecture by making it set the divecomputer in

This has become a bit of a catch-all overhaul of a large portion of the
planner - I started out wanting to improve the CCR mode, but then as I
started pulling all the other threads that needed addressing started to
come with it.
Improve how the gas selection is handled when planning dives in CCR
mode, by making the type (OC / CCR) of segments dependent on the gas use
type that was set for the selected gas.
Add a preference to allow the user to chose to use OC gases as diluent,
in a similar fashion to the original implementation.
Hide gases that cannot be used in the currently selected dive mode in
all drop downs.
Include usage type in gas names if this is needed.
Hide columns and disable elements in the 'Dive planner points' table if
they can they can not be edited in the curently selected dive mode.
Visually identify gases and usage types that are not appropriate for the
currently selected dive mode.
Move the 'Dive mode' selection to the top of the planner view, to
accommodate the fact that this is a property of the dive and not a
planner setting.
Show a warning instead of the dive plan if the plan contains gases that
are not usable in the selected dive mode.
Fix the data entry for the setpoint in the 'Dive planner points' table.
Fix problems with enabling / disabling planner settings when switching
between dive modes.
Refactor some names to make them more appropriate for their current
usage.
One point that is still open is to hide gas usage graphs in the planner
profile if the gas isn't used for OC, as there is no way to meaningfully
interpolate such usage.

Since struct divecomputer is now fully C++ (i.e. cleans up
after itself), we can simply turn the list of divecomputers
into an std::vector<>. This makes the code quite a bit simpler,
because the first divecomputer was actually a subobject.
Yes, this makes the common case of a single divecomputer a
little bit less efficient, but it really shouldn't matter.
If it does, we can still write a special std::vector<>-
like container that keeps the first element inline.
This change makes pointers-to-divecomputers not stable.
So always access the divecomputer via its index. As
far as I can tell, most of the code already does this.

This is a rather long commit, because it refactors lots of the event
code from pointer to value semantics: pointers to entries in an
std::vector<> are not stable, so better use indexes.
To step through the event-list at diven time stamps, add *_loop classes,
which encapsulate state that had to be manually handled before by
the caller. I'm not happy about the interface, but it tries to
mirror the one we had before.

- show the correct gasmix in the profile;
- make gases available for gas switches in the profile after they have
been added;
- persist gas changes;
- add air as a default gas when adding a dive.
This still has problems when undoing a gas switch - instead of
completely removing the gas switch it is just moved to the next point in the
profile.

printf() is a horrible interface as it does no type checking.
Let's at least use the compiler to check format strings and

Currently, the "hide event" status is lost when switching dives.
Save it in the event struct instead to make it persistent.
In the future we might save this information to the log file.
Then this should be integrated in the undo-system.
This commit also makes the "unhide events" menu entry more
fine grained: It now differentiates between individual
events and event types.
Note this adds an additional field to the event structure.
There is a "deleted" field that is used internally for
book-keeping, but probably should be removed. Not touching
this at the moment as long as this is C-only code. When/if
switching to C++ we can make the event linked list a table,
which will make this much simpler.

Reinstate the hiding of events by event type across
all dives in the log. This was unintentionally removed in #3948.
Also change the event type to be specific to name and severity, and fix
bug causing 'Unhide all events' to not show when only individual events
were hidden.
This still leaves the inconsistency that hiding of similar events is
persisted across the switch between dives, but hiding of individual
events is lost when switching dives, which is mildly confusing.
Follow-up to #4092.

This does two independent things:
It sets the planner state early enough so the appropriate
default profile for the planner is created (without
safety stop).
Upon cancelling the planner, it resets the profile widget
to profile more (rather than planner) as otherwise upon
the next change into the planner the planner model is
not properly initialized.

With Qt-containers, this might be a small pessimization, because

When zoomed in, the profile position was moved by hovering with
the mouse. What a horrible user experience. This is especially
useless if we want to implement an interactive profile on mobile.
Instead, let the user start the panning with a mouse click. The
code is somewhat nasty, because the position is given as a
real in the [0,1] range, which represents all possible positions
from completely to the left to completely to the right.
This commit also removes the restriction that the planner handles
can only be moved when fully zoomed out. It is not completely
clear what the implications are. Let's see.

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.

When in the planner, ESC should cancel the plan.
However, when the user manipulates the dive-handles in the
profile and presses ESC, first nothing happens, then an obscure
message appears.
The reason is that ESC "shortcuts" are introduced in two places.
To fix this, remove the ESC shortcut in the profile (the planner
widget cancels the plan anyway) and replace all the shortcuts in
the profile with a simple override of the keyPressEvent().
The latter is not strictly necessary, but hopefully avoids further
complications with multiple shortcuts. And the code is easier
to follow too.

In planner and edit mode, the cursor position is indicated using
crosshairs. They broke when changing to absolute scaling.
To fix them, remember the plot-area in the profile scene and
draw the crosshairs only inside this area (not on top of axes).
However, limit the position of the horizontal line to the
actual profile (dont paint inside the partial pressure, etc
graphs). The vertical line is painted above those graphs, so
that a timestamp can be related to partial pressure, tissue
loading, etc.
Also, set the z-value of the crosshairs. It was painted
inconsistently above some and below other chart features.
