macro: Add macro PA_UNUSED
the macro PA_UNUSED may be used to suppress a warning when a variable
is not used, or assigned and never used; this typically happens
when the only use of the variable is within an assert() that can
be optimized away (i.e. with NDEBUG set)
has an effect with GCC only
v2: (thanks to Alexander Patrakov)
* fix patch subject/description
