Convert a few more function definitions to prototype style.

This patch converts a few more function definitions in glibc from
old-style K&R to prototype style.  This is sufficient to build and
test on x86_64 and x86 with -Wold-style-definition (I'll test on some
more architectures before proposing the actual addition of
-Wold-style-definition).

Tested for x86_64 and x86 with -Wold-style-definition in use
(testsuite - this patch affects files containing assertions).

	* io/fts.c (fts_open): Convert to prototype-style function
	definition.
	* malloc/mcheck.c (mcheck): Likewise.
	(mcheck_pedantic): Likewise.
	* posix/regexec.c (re_search_2_stub): Likewise.  Use
	internal_function.
	(re_search_internal): Likewise.
	* resolv/res_init.c [RESOLVSORT] (net_mask): Convert to
	prototype-style function definition.
	* sunrpc/clnt_udp.c (clntudp_call): Likewise.
	* sunrpc/pmap_rmt.c (clnt_broadcast): Likewise.
	* sunrpc/rpcsvc/rusers.x (xdr_utmp): Likewise.
	(xdr_utmpptr): Likewise.
	(xdr_utmparr): Likewise.
	(xdr_utmpidle): Likewise.
	(xdr_utmpidleptr): Likewise.
	(xdr_utmpidlearr): Likewise.
