* printf/asprntffuns.c: New file.

	* printf/asprntffuns.c, printf/vasprintf.c, gmp-impl.h
	(__gmp_asprintf_memory, __gmp_asprintf_reps, __gmp_asprintf_final):
	Move to asprntffuns.c, rename to __gmp and make global, remove
	spurious formal parameters from __gmp_asprintf_final.

+   exists, or to support mpz_out_ostream if C++ has been enabled.  (It'd be
