Subject: Decorate C prototypes
Hi,
it turns out that there are several delcarations of C functions that
miss my warning (since they are not being compiled locally) but needs
decorations.
I verified the markers with what builtins.def and glibc does.

Tested on x86_64-linux, OK?
	* include/c_std/cstdlib (abort, exit, _Exit): Mark noreturn throw ().
	(atexit, atoll, stroll, strtoull): Mark throw ()
	* include/c_std/cstdio (snprintf, vsnprintf, vscanf): Mark throw ().
	* include/c_std/cwchar (wcstold, wcstoll, wcstoull): Mark throw ().
	* include/c_global/cstdlib (abort, exit, _Exit): Mark noreturn throw ().
	(atexit, atoll, stroll, strtoull): Mark throw ()
	* include/c_global/cstdio (snprintf, vsnprintf, vscanf): Mark throw ().
	* include/c_wchar/cstdio (snprintf, vsnprintf, vscanf): Mark throw ().
