* include/rpc/clnt.h: Declare __libc_clntudp_bufcreate and

	__libc_clntudp_bufcreate_internal.
	* include/sys/socket.h: Declare __have_sock_cloexec.
	* socket/Makefile (aux): Add have_sock_cloexec.
	* socket/have_sock_cloexec.c: New file.
	* sunrpc/clnt_udp.h (clntudp_bufcreate): Now a wrapper around
	__libc_clntudp_bufcreate.
	(__libc_clntudp_bufcreate): Former implementation of clntudp_bufcreate
	which takes an additional parameter.  Create socket with non-blocking
	mode and close-on-exec flag set, if wanted.
	* sunrpc/Versions: Export __libc_clntudp_bufcreate@GLIBC_PRIVATE.
	* nis/ypclnt.c (yp_bind_client_create): Use __libc_clntpudp_bufcreate
	instead of clntudp_create.  The socket has already the close-on-exec
	flag set if SOCK_CLOEXEC is defined.
