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!

When merging two dives, if a divesite is chosen that doesn't
have a GPS location, but another divesite has a GPS location,
then the GPS location of the former is set to that of the
latter.
However, that was done outside of the undo system, so that
it is not undone and the frontend is not made aware of the
change.
Fix this. To simplify things, move the code from the undo
machinery to the core.

All callers were just using that member to set the dive_site
in the resulting dive. We might just do that in the called
function [merge_dives()].

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.

The copy/pasting of dive-sites was fundamentally broken in at least two
ways:
1) The dive-site pointer in struct dive was simply overwritten, which
breaks internal consistency. Also, no dive-site changed signals where
sent.
2) The copied dive-site was stored as a pointer in a struct dive. Thus,
the user could copy a dive, then delete the dive-site and paste.
This would lead to a dangling pointer and ultimately crash the
application.
Fix this by storing the UUID of the dive-site, not a pointer.
To do that, don't store a copy of the dive, but collect all
the data in a `dive_paste_data` structure.
If the dive site has been deleted on paste, do nothing.
Send the appropriate signals on pasting.
The mobile version had an additional bug: It kept a pointer to the
dive to be copied, which might become stale by undo.

Feels natural in a C++ code base.
In analogy to other tables, this creates a struct that derives
from std::vector<>. This is generally frowned upon, but it works
and is the pragmatic thing for now. If someone wants to "fix" that,
they may just do it.

The important point is that this now takes a reference that
avoid string copying. The old code used C-strings and therefore
copy-semantics were OK.

This accesses the global dive_table, so make this explicit.
Since force_fixup_dive() and default_dive() use fixup_dive(),
also move them to struct dive_table.

Before, a non-owning pointer was passed and the dive moved
away from the dive. Instead, let the caller decide if they
still want to keep a copy of the dive, or give up ownership:
In MainWindow and QMLManager new dives are generated, so
one might just as well give up ownership. In contrast,
the planner works on a copy (originally the infamous
"displayed_dive") and now moves the data manually.
This commit also removes duplicate code, by moving the
"create default dive" code from MainWindow and QMLManager
to struct dive.
Finally, determination of the "time zone offset" is not done
in POSIX, since we want to avoid calls form the core into
Qt.

There was a weird asymmetry, where the undo-commands would
register the fulltext index of the dive, but the core would
unregister the fulltext index in the "unregister_dive()"
function.
To make this more logical, create a "register_dive()" function
in core that does registers the fulltext index.

The dive_table will be converted into a table of owning pointers.
Since the trip has only non-owning pointers to dives, turn
its dive_table into an std::vector<dive *>.
