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));

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.

914cdb102b Fix Suunto FIT file import dive duration mis-calculation
The Suunto FIT files end up creating a sample every second, but a lot of
those samples with no depth information, marked as "depth.mm" being negative.

That doesn't end up being a problem for subsurface, _except_ that it
really confuses our "dc_fixup_duration()" logic, and the dive duration
ends up being completely nonsensical (generally roughly by a factor of
five: every tenth sample has a depth, and we only count samples that
"begin or end under water" as being relevant for the dive duration, so
two out of the ten samples will count towards the dive time).

Saving the dive will then not save these invalid depths, so saving and
reloading the dive ends up fixing the dive duration calculation.

The fix is trivial - we just ignore samples with negative depth in
dc_fixup_duration().

The FIT file parser should probably be taught to not even bother sending
empty samples to subsurface, but that's a separate cleanup.  This fixes
the actual bad behavior.

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.

c27314d603 core: replace add_sample() by append_sample()
add_sample() was used in only one place, and the return value was
always ignored. It took a time parameter, suggesting that a sample
could be added anywhere, but in reality the sample was added at
the end of the list. It used prepare_sample() that copies data
from the previous sample, just to overwrite it with the newly
added sample.

All in all very weird. Simplify the function: just append the
passed in sample and name it accordingly.

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.

a01ab81713 cleanup: fold core/divecomputer.cpp into core/device.c
core/device.h was declaring a number of functions that were related
to divecomputers (dcs): creating a fake dc for manually entered dives
and registering / accessing dc nicknames. On could argue whether
these should be lumped together, but it is what it is.

However, part of that was implemented in C++/Qt code in a separate
core/divecomputer.cpp file. Some function therein where only
accessible to C++ and declared in core/divecomputer.h.

All in all, a big mess. Let's simply combine the files and
conditionally compile the C++-only functions depending on
the __cplusplus define.

Yes, that means turning device.c into device.cpp. A brave soul
might turn the C++/Qt code into C code if they whish later on.

17526ded58 cleanup: move clearing of device nodes to clear_dive_file_data()
It makes no sense to keep the device nodes if all the other data
is cleared. Let's do this automatically and not explicitly.
This ensures that the function is also called on mobile.
Currently it was only called on desktop.

Weirdly, the parser-tests were expecting that the device nodes
were not reset by clear_dive_file_data() and therefore divecomputers
were accumulating in the test results. Thus, the additional
computers had to be removed from the expected test results.

b72cc1f317 Cleanup: consistently use qPrintable()

This is concise, consistent and - in principle - more performant than

7be962bfc2 Move subsurface-core to core and qt-mobile to mobile-widgets
Having subsurface-core as a directory name really messes with
autocomplete and is obviously redundant. Simmilarly, qt-mobile caused an
autocomplete conflict and also was inconsistent with the desktop-widget
name for the directory containing the "other" UI.

And while cleaning up the resulting change in the path name for include
files, I decided to clean up those even more to make them consistent
overall.

This could have been handled in more commits, but since this requires a
make clean before the build, it seemed more sensible to do it all in one.
