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
the constructor - using the same loop for multiple dive computers is not
intended to work.
Also change `next()` in `divemode_loop` to `at()` to make the name more

Fix the initial gasmix that is shown in the tank bar of the profile.
Also add a meaningful gas name for gases with negative values for
percentages.
@bstoeger: This is a side effect of the `event_loop` functionality
introduced as part of #4198. In the case of an `event_loop("gasmix")`
this does not take into account the edge case where there is no
gaschange event at the very beginning of the dive, and the first gasmix
is implicitly used as the starting gasmix. This happens for planned and
manually added dives, but also for some dive computers.
We are using the
same kind of loop in a number of other places in `core/profile.cpp`,
`core/dive.cpp`, `core/gaspressures.cpp`, and `profile-widget/tankitem.cpp`,
and I am wondering if we should be converting these to use
`gasmix_loop` instead to avoid being bit by this special case?

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.

Not strictly necessary, but more idiomatic C++ and less

Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
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.

This is a hairy one, because the sample code is rather tricky.
There was a pattern of looping through pairs of adjacent samples,
for interpolation purposes. Add an range adapter to generalize
such loops.
Removes the finish_sample() function: The code would call
prepare_sample() to start parsing of samples and then
finish_sample() to actuall add it. I.e. a kind of commit().
Since, with one exception, all users of prepare_sample()
called finish_sample() in all code paths, we might just add
the sample in the first place. The exception was sample_end()
in parse.cpp. This brings a small change: samples are now
added, even if they could only be parsed partially. I doubt
that this makes any difference, since it will only happen
for broken divelogs anyway.

Use more C++ style memory management for plot_info: Use std::vector
for array data. Return the plot_info instead of filling an output
parameter. Add a constructor/destructor pair so that the caller
isn't bothered with memory management.
The bulk of the commit is replacement of pointers with references,
which is kind of gratuitous. But I started and then went on...

- 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.

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.

Currently the event type code uses libdivecomputer's flags
to differentiate between events. Make this explicit and extract
the event severity.
The reason is that later we want to be more explicit about showing/
hiding events and thereto we must format the name of events.
Moreover, this encapsulates the complexities of extracting
the severity in the event code (that used to be in the profile
code).

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.

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.

This tries to encapsulate the management of the current dive and
divecomputer in the selection code. The current dive is alreay
set by setSelection(). Add a new parameter to also set the
current divecomputer. If -1 is passed, then the current
computer number is remained. This will allow us to audit the code.
Because for now, the whole "current dive computer" thing seems
to be ill-defined.
This fixes a bug: the dive-computer number wasn't validated
when making a new dive the current dive. The new code has some
drawbacks though: when selecting a whole trip, the validation
will be called for all dives in the trip and thus the dive computer
number will depend on the dive with the lowest amount of dive
computers in the trip. This will need to be fixed.

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