Labels have function scope. Try to avoid naming conflicts as good as
possible.

P99_AALLOC allocates a matrix with the sizes taken from another one
P99_ANAME creates a list of variable names needed to for P99_CA_CALL and similar

we recast because of const-qualification

better not reference the macro name in the argument documentations. this makes doxygen expand it repeatedly

doxygen is quite picky in what is possible with macros
basically things like p99_generic.h are not possible to map well to it,
so avoid that doxygen ever sees this complicated code

plus some minor doc stuff here and there

as a side effect have _Atomic operations also lock-free for all types
that have the same size as some unsigned integer type, with the notable
exception of floating point types. For those we have to use an
atomic_flag to protect them if they are used with atomic arithmetic
operations.

also classify the lock-free types much more systematically

first argument

in fact that compiler just explodes with P99

by that we can now better check automatically if there are macro
arguments that get evaluated multiple times although they shouldn't

in many cases this will result in a better documentation of the
properties in doxygen

not perfect, but better than nothing
