Downloder builds pull in show_computer_list() from
downloadfromdcthread.cpp, but it's declared as extern "C". With 76c2069f
having converted subsurfacestartup.c to .cpp, we can remove the extern

Add 'Country' to the fields that are indexed for fulltext search - this
seems to be a quite intuitive choice as 'Country' is also a field that
is available in the dive list view.

printf() is a horrible interface as it does no type checking.
Let's at least use the compiler to check format strings and
arguments. This obviously doesn't work for translated strings
and using report_error on translated strings is dubious. But OK.
Had to convert a number of report_error() calls to supress
warnings.

When initializing a string with multiple characters, first
comes the length, then the size. Not the other way around.

On initialization, the old code searched for the first language
code containing a '-'. However, my Qt version gives de-Latn-DE
as the first entry. That messed up the preferences code: it
didn't recognize that entry. Thus, simply opening and closing
the preferences switched the language to Bulgarian.

There was a pattern of code like
match_action(line, state, dive_action, ARRAY_SIZE(dive_action));
The doubling of the array might cause copy & paste errors, where
only one array is replaced.
Therefore, determine the length of the array with (hopefully
easily understood) template tricksery.

When iterating over the converted strings of a line, the
first entry of the array would be popped off, leading to
a full copy of the remaining array.
Instead, use an index in the parser state.

The converted strings were stored in a membuffer and later
converted to std::strings. Generate an std::string directly
to avoid unnecessary copying.
Ultimately, when the core structures are converted to
std::string, there should be no copying of the string data
at all (unless formatting is applied or small string
optimization kicks in, of course).

Create a format_string_std function that works like format_string,
but does return a std::string instead of a strdup()ed C string.
Make it a global function to be used in other parts of the code.

This avoid memory-management troubles. Had to convert a few
of the parsers (cochran, datatrak, liquivision) to C++.
Also had to convert libdivecomputer.c. This was less
painful than expected.
std::string is used because parts of the code assumes
that the data is null terminated after the last character
of the data. std::string does precisely that.
One disadvantage is that std::string clears its memory
when resizing / initializing. Thus we read the file onto
freshly cleared data, which some might thing is a
performance regression. Until someone shows me that this
matters, I don't care.

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

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()

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.
