[fweimer at redhat dot com (Florian Weimer)]

2017-08-16  Florian Weimer  <fweimer@redhat.com>

	* include/rpc/pmap_clnt.h (__get_socket): Remove
	internal_function.
	* sunrpc/auth_des.c (synchronize): Likewise.
	* sunrpc/auth_unix.c (marshal_new_auth): Likewise.
	* sunrpc/clnt_perr.c (auth_errmsg): Likewise.
	* sunrpc/des_impl.c (des_encrypt, des_set_key): Likewise.
	* sunrpc/key_call.c (key_call_keyenvoy, key_call_socket)
	(key_call): Likewise.
	* sunrpc/pm_getport.c (__get_socket): Likewise.
	* sunrpc/pmap_rmt.c (getbroadcastnets): Likewise.
	* sunrpc/svc_unix.c (makefd_xprt): Likewise.
	* sunrpc/svc_tcp.c (makefd_xprt): Likewise.
	* sunrpc/svcauth_des.c (cache_init, cache_spot, cache_ref)
	(invalidate): Likewise.
	* sunrpc/xcrypt.c (hexval, hex2bin, bin2hex): Likewise.
	* sunrpc/xdr_rec.c (fix_buf_size, skip_input_bytes, flush_out)
	(set_input_fragment, get_input_bytes): Likewise.
