ae81b42fe2 core: introduce a few user-defined literals for unit types
Thise makes initialization of unit types more palatable.

For example:

    surface.time = sample.time - duration_t { .seconds = 20 };
=>  surface.time = sample.time - 20_sec;

    delta_depth.mm = feet_to_mm(1.0); // 1ft
=>  delta_depth = 1_ft;

    get_cylinderid_at_time(..., { .seconds = 20 * 60 + 1 }));
=>  get_cylinderid_at_time(..., 20_min + 1_sec));

110e64bc66 general: simplify a few unit manipulations
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.

3e006e678a planner: don't use fixed size deco stop table
This was quite ominous: a 60-element fixed size table was
passed as argument to plan(). But there was no check for 60
anywhere? Use a dynamic vector instead.

The whole thing is weird, as the depth of the decostop table
doesn't seem to be used.

ee25e8a1db Refactoring: Improve event_loop.
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
aligned with its function.

33bb39f1ca Planner: Fix Warning from Coverity.
Fix an interger overflow warning when parsing setpoints.

@bstoeger: In the end it turned out that this parser was only used in
one place in the planner UI, and it was simplest to switch this to
using `QVariant.toFloat()` in the model itself, which is consistent how
the rest of the input values is parsed and validated.

2d8e343221 Planner: Improve Gas Handling in CCR Mode.
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.

284582d2e8 core: turn divecomputer list into std::vector<>
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.

27dbdd35c6 core: turn event-list of divecomputer into std::vector<>
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.

f120fecccb core: use std::vector<> to store divecomputer samples
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.

408b31b6ce core: default initialize units-type objects to 0
Makes the code much nicer to read.

Default initialize cylinder_t to the empty cylinder.

This produces lots of warnings, because most structure are now
not PODs anymore and shouldn't be erased using memset().

These memset()s will be removed one-by-one and replaced by
proper constructors.

The whole ordeal made it necessary to add a constructor to
struct event. To simplify things the whole optimization of
the variable-size event names was removed. In upcoming commits
this will be replaced by std::string anyway.

528532572f Planner: Fix Editing of Plans in Multi-Divecomputer Dives.
Currently editing of planned dives that have been merged with actual
(logged) dives only works if the 'Planned dive' divecomputer is the
first divecomputer, and this divecomputer is selected when clicking
'Edit planned dive'. In other cases the profile of the first
divecomputer is overlaid with the profile of the planned dive, and the
first divecomputer's profile is overwritten when saving the dive plan.
Fix this problem.

Triggered by @SeppoTakalo's comment (https://github.com/subsurface/subsurface/issues/1913#issuecomment-2075562119): Users don't like that planned dives show up as their own entries in the dive list, so being able to merge them with the actual dive after it has been executed is a good feature - but this wasn't working well until now.
