* resolv/res_send.c (__libc_res_nsend): Take additional parameter.cvs/fedora-glibc-20080728T2320

	Use it instead of locally defined resplen2 variable.
	(res_nsend): Adjust for __libc_res_nsend interface change.
	(send_vc): Initialize *resplen2 if necessary.  Read length of
	package into an appropriately aligned variable.  Store converted length
	in new variable and use it appropriately.
	Add branch prediction help.
	* resolv/res_query.c (__libc_res_nquery): Take additional parameter
	and pass it on to __libc_res_nsend.  Adjust all callers.
	(__libc_res_nsearch): Likewise.
	(__libc_res_nqeurydomain): Likewise.
	* resolv/nss_dns/dns-host.c: Adjust for __libc_res_nsearch interface
	change.
	(_nss_dns_gethostbyname4): Don't unconditionally allocate tmp array.
	Define resplen2 variable and pass it to __libc_res_nsearch and then
	to gaih_getanswer.
	(getanswer_r): In case of incorrect DNS data don't overread buffer.
	Add branch prediction.
	(gaih_getanswer_slice): Likewise.  Check for invalid data types.
	(gaih_getanswer): Don't decode second slice if first one failed due
	to a too small buffer.  Don't let not found status of second
	decoder shadow results of the first.
	* resolv/gethnamaddr.c (gethostbyname2): Adjust for __libc_res_nsearch
	and __libc_res_nquery interface changes
	(gethostbyaddr): Adjust for __libc_res_nquery interface change.
	* include/resolv.h: Adjust prototypes for __libc_res_nquery,
	__libc_res_nsearch, and __libc_res_nsend.
	* resolv/nss_dns/dns-canon.c: Adjust for __libc_res_nquery interface
	change.
	* resolv/nss_dns/dns-network.c: Adjust for __libc_res_nquery and
	__libc_res_nsearch interface changes.
