	Add basic support for RPC over IPv6:
	* sunrpc/rpc/svc.h (struct SVCXPRT): Use `struct sockaddr_storage'
	for remote address.
	(svcudp6_create, svcudp6_bufcreate, svctcp6_create): New
	prototypes.
	* sunrpc/rpc/clnt.h (clnttcp6_create, clntudp6_create,
	clntudp6_bufcreate): New prototypes.
	* inet/netinet/in.h (bindresport6): Likewise.
	* sunrpc/Makefile (routines): Add svc_tcp6, svc_udp6, bindrsvprt6.
	* sunrpc/Versions: Add svcfd6_create, svctcp6_create,
	svcudp6_create, svcudp6_bufcreate, svcudp6_enablecache,
	bindresvport6 for GLIBC_2.2.
	* sunrpc/rpc_main.c: Support `tcp6' and `udp6' transport types.
	* sunrpc/rpc_svcout.c: Likewise.
	* sunrpc/svc_tcp.c (rendezvous_request): Use memcpy rather than
