Add changes which were in this form in the original patch by
	Eric Norum <eric.norum@usask.ca>.
	* include/rpc/rpc.h: Remove svc_fdset, rpc_createerr, svc_pollfd, and
	svc_max_pollfd.
	* sunrpc/rpc/rpc.h: Declare __rpc_thread_svc_fdset,
	__rpc_thread_createerr, __rpc_thread_svc_pollfd, and
	__rpc_thread_svc_max_pollfd.
	Define svc_fdset, get_rpc_createerr, svc_pollfd, and
	svc_max_pollfd.
	* sunrpc/rpc_thread.c: Handle first thread special, it uses the
	global variables.
	Define __rpc_thread_svc_fdset, __rpc_thread_createerr,
	__rpc_thread_svc_pollfd, and __rpc_thread_svc_max_pollfd.
	* sunrpc/Versions [libc] (GLIBC_2.2.3): Export  __rpc_thread_svc_fdset,
	__rpc_thread_createerr, __rpc_thread_svc_pollfd, and
	__rpc_thread_svc_max_pollfd.
	* sunrpc/clnt_gen.c: Replace use of rpc_createerr by call to
	get_rpc_createerr.
	* sunrpc/clnt_perr.c: Likewise.
	* sunrpc/clnt_simp.c: Likewise.
	* sunrpc/clnt_tcp.c: Likewise.
	* sunrpc/clnt_udp.c: Likewise.
	* sunrpc/clnt_unix.c: Likewise.
	* sunrpc/pm_getport.c: Likewise.
