sunrpc: Remove stray exports without --enable-obsolete-rpc [BZ #23166]
This is needed to avoid a warning when linking against libtirpc: /lib64/libc.so.6: warning: common of `rpc_createerr@@TIRPC_0.3.0' overridden by definition /usr/lib64/libtirpc.so: warning: defined here This ld warning is not enabled by default; -Wl,--warn-common enables it.

+ [BZ #23166]
+ * include/rpc/clnt.h (rpc_createerr): Declare hidden alias.
+ * include/rpc/svc.h (svc_pollfd, svc_max_pollfd, svc_fdset):
+ Likewise.
+ * sunrpc/rpc_common.c (svc_fdset, rpc_createerr, svc_pollfd)
+ (svc_max_pollfd): Add nocommon attribute and hidden alias. Do not
+ export without --enable-obsolete-rpc.
+ * sunrpc/svcauth_des.c (svcauthdes_stats): Turn into compatibility
+ symbol. This should not have been exported, ever.
