To my understanding, declaring empty parameter lists using "(void)"
is an artifact from the bad old K&R times, when functions were
declared without(!) parameters. Which in hindsight was an absolute
recipe for disaster. So for backwards compatibility, functions
without parameters had to be declared using "(void)" as "()"
could also mean "any function".
That was 40 years ago. Meanwhile, C++ introduced references,
which made it a necessity to declare the function parameters.
So "(void)" is redundant and inconsistent in C++ code and
just makes no sense.
Remove it.

Since the taxonomy is now a real C++ struct with constructor
and destructor, dive_site has to be converted to C++ as well.
A bit hairy for now, but will ultimately be distinctly simpler.

Fix loading of the negation of filter conditions. Unlike other
conditions that are persisted as `<key>="<value>"`, this is persisted
to git as `negate`.
This fix remediates this for all cases where the condition has already
been saved to the cloud storage.
Saving to XML takes a different approach and indicates negated
conditions with `negate="1"`, making it identical to all other
attributes. The question is if this approach should be implemented in
addition to the above fix, in order to unify the storage format.
Fixes#4246.

Had to rewrite the thing, because gcc's warnings don't work
with templatized var-args. Since there is no string-format.cpp
and I didn't want to inline it, moved it to format.cpp.
String formatting is distributed around at least four
headers: membuffer.h, subsurface-string.h, format.h
and format-string.h. This really should be unified!

Quite a bit of fallout in users of this structure.
Conveniently, since git-access.cpp is now C++ we can move
some helpers from the monstrous qthelper.cpp to git-access.cpp.

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).

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.
