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!

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.

Feels natural in a C++ code base.
Change the function to return a weight_t. Sadly, use of the

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.

This is a messy commit, because the "qPref" system relies

Since everything is C++ now, we can use unique_ptr<>s. This makes
the code significantly shorter, because we can now use the default
move constructor and assignment operators.
This has a semantic change when std::move()-ing the divelog:
now not the contents of the tables are moved, but the pointers.
That is, the moved-from object now has no more tables and
must not be used anymore. This made it necessary to replace
std::move()s by std::swap()s. In that regard, the old code was
in principle broken: it used moved-from objects, which may work
but usually doesn't.
This commit adds a myriad of .get() function calls where the code
expects a C-style pointer. The plan is to remove virtually all of
them, when we move free-standing functions into the class it acts
on. Or, replace C-style pointers by references where we don't support
NULL.

The old code was wild: For the yearly statistics it would allocate
one entry per dive in the log. Of course, it would also leak
C-style strings.
Convert the whole thing to somewhat idiomatic C++.
Somewhat wasted work, because I'd like to convert the whole thing
to the new statistics code. But let's finish the conversion to C++

The strtod_flags() function allowed for fine control of how to
parse strings. However, only two different modes were actually
used: ascii mode ("C" locale) and permissive mode (accept ","
and "." as decimal separator).
The former had already its own function name (ascii_strtod).
Make the latter a separatge function as well (permissive_strtod)
and remove all the flags rigmarole.

The old code was leaking memory. Use std::unique_ptr<> for
ownership management.
This is still very primitive and divetags are kept during
application lifetime. There should probably be some form
of reference counting. And the taglist should not be global,
but attached to the divelog.

Let's use std::string in the core. Notably, I'd like to make
the numerous main() functions mostly independent of Qt. Some
things will have to remain, such as argument parsing, of course.
This changes the API: instead of returning an error code and
taking a pointer to the actual return-value, return an
std::optional<std::string>> that is set if the function succeeds.
Returning an empty string in the error case might be simpler,
but oh well...

Q_FOREACH and foreach are anachronisms.
Range based for may cause a performance regression: it can
lead to a copy of shared containers (one reason why Qt's
COW containers are broken). However, as long as there is no
user noticeable delay, there is no point in analyzing each case.
And also no point in slapping an 'asConst' on every container

The parser API was very annoying, as a number of tables
to-be-filled were passed in as pointers. The goal of this
commit is to collect all these tables in a single struct.
This should make it (more or less) clear what is actually
written into the divelog files.
Moreover, it should now be rather easy to search for
instances, where the global logfile is accessed (and it
turns out that there are many!).
The divelog struct does not contain the tables as substructs,
but only collects pointers. The idea is that the "divelog.h"
file can be included without all the other files describing
the numerous tables.
To make it easier to use from C++ parts of the code, the
struct implements a constructor and a destructor. Sadly,
we can't use smart pointers, since the pointers are accessed
from C code. Therfore the constructor and destructor are
quite complex.
The whole commit is large, but was mostly an automatic
conversion.
One oddity of note: the divelog structure also contains
the "autogroup" flag, since that is saved in the divelog.
This actually fixes a bug: Before, when importing dives
from a different log, the autogroup flag was overwritten.
This was probably not intended and does not happen anymore.

Tweak the Lat/Long coordinate parser to allow coordinates of the form:
12.1049° N, 68.2296° W
The coordinate parser works by tokenizing coordinates one at a time.
Consequently it is invoked twice on user input to get latitude and then
longitude. Normally, after parsing the first coordinate, intervening
characters such as , or ; and any whitespace would be discarded from the
input before parsing the second coordinate. Prior to this patch, if the
coordinate format was in degrees followed by a sign (N is a sign in this
example), the parser would skip the bit of code that fast forwards past
any intervening separators and whitespace (, in this example). This
resulted in coordinates of this form not being accepted, because the
second parse would start with , 68.2296° W and reject this as an invalid
coordinate.
To rectify this, the bit of code that fast forwards past separators and
whitespace has been broken out from the tokenization loop and performed
as a final step after a single coordinate has been completely parsed and
validated. Doing it this way makes it independent of the state of the
tokenizer, so that the fast-forward code will always execute once a
coordinate has been successfully parsed.
I've also centralized the list of allowed separators into its own static
string; this is necessary as part of the patch but should also make
allowing additional separator characters between coordinates trivial in
the future, if needed.

To enable grouping by trip in the statistics module, split
the get_trip_title() function in a version that appends
a "(n dive(s)" string an one that doesn't. The statistics
module doesn't want that added string, since it displays
the number of dives in a different way.
Also, move the functions to string-format.h, where these
are collected. And rename them to camelCase. Yes, it's
ugly, but consistent with most other C++ code in the code
base.
