Return an std::string to avoid memory management headaches.
While doing that, convert time.c to C++ so that
format_datetime directly returns an std::string.

This was very annoying, because the old code was not const-clean
at all and trampled all over buffers. This makes the new code
pretty messy for now.

The automatic conversion from char * to QVariant failed to
compile for me. Let's hint that this should be interpreted
as a string. No idea, why this happens for me, but apparently
not on CI.

Make the memory management easier to follow. I feel that the old
code was leaking left and right, but not sure because it was so
intractable.

Simplifies memory management. Think about unglobalizing this,
once everything is in C++ so that we can put an std::string
into struct divelog.

This includes using the C++ version of membuffer. There appears
to not have been a leak, because the buffer is freed in
flush_buffer(), but usage was somewhat inconsistent and hard to
follow.
Also, convert some string handling to std::string to avoid free()
madness.

get_changes_made(), subsurface_user_agent() and normalize_cloud_name()
are only called from C++.
Avoids having to manually free the returned value and is therefore
more robust against leaks.

The code is now much easier to check for memory leaks,
since there are no explicit free()s. Yes, memory is not
released immediately, but that should be of no concern.

This changes default behavior when creating a sample struct
in C++ code: it is now initialized to default values. If this
ever turns out to be a performance problem, we can either add
additional constructors or use special functions that do
not initialize memory, such as make_unique_for_overwrite.
This removes non-standard (respectively >C++20) constructs,
namely designated initializers.

Avoid error-prone malloc/free pairs. This uses somewhat
obscure constructs to stay as close as possible to the
original C code. Notably, it uses mostly unique_ptr<T[]>
which doesn't store the length of the array, because the
length is supposed to be known.

Long term project: convert core to C++ so that we can
use higer-level constructs, notably std::vector<>.
This does not change any code - only fixes compile issues.
Mostly casting of (void *) to the proper type. Also designated
initialization of the sample struct had to be rearranged.

In the core, we usually want C strings, not QStrings. Therefore,
make translated C strings directly available from C++.

The function clear_*_table frees all elements of the table.
However, persumably as a performance feature, it kept the
memory of the table itselt (i.e. it only reset the number of
elements but kept the capacity).
That is fine if the table is reused later. However, this
function was also used when freeing the table and this
would leak the table memory.
This commit frees the table memory. An alternative would
be to have separate clear_*_table and free_*_table functions.
But let's wait with that until we port the table code to C++.
Then this will be "automatically" fixed.

Firstly, why calculate something when the next statement is a return
anyway.
Secondly, the calculation subtracts two completely unrelated pointers.
This must be some code reshuffling artifact.

Determine grade based on whether we actually managed to check out the
buildnumber.
This assumes that the tree is clean for building a stable snap (one that
can be published to candidate and stable channels).
