* sunrpc/xcrypt.c (passwd2des_internal): Renamed fom passwd2des.

	(passwd2des): Define it as an alias.
	(xencrypt, xdecrypt): Call passwd2des_internal instead of passwd2des.

	* include/sys/sysctl.h (__sysctl): Add libc_hidden_proto.
	* sysdeps/unix/sysv/linux/sysctl.c (__sysctl): Add libc_hidden_def.

	* include/rpc/xdr.h (xdrstdio_create): Add libc_hidden_proto.
	* sunrpc/xdr_stdio.c (xdrstdio_create): Add libc_hidden_def.
