Update.
	* sunrpc/Makefile (routines): Add rpc_thread.
	(CPPFLAGS): Add -D_RPC_THREAD_SAFE.
	* sunrpc/rpc_thread.c: New file.
	* sunrpc/Versions [libc] (GLIBC_2.2.3): Export __rpc_thread_destroy.
	* sunrpc/auth_none.c: Don't use global variables.  Access state in
	thread-local storage.
	* sunrpc/clnt_perr.c: Likewise.
	* sunrpc/clnt_raw.c: Likewise.
	* sunrpc/clnt_simp.c: Likewise.
	* sunrpc/key_call.c: Likewise.
	* sunrpc/rpc_common.c: Likewise.
	* sunrpc/svc.c: Likewise.
	* sunrpc/svc_raw.c: Likewise.
	* sunrpc/svc_simple.c: Likewise.
	* sunrpc/svcauth_des.c: Likewise.
	* hurd/hurd/threadvar.h (enum __hurd_threadvar_index): Add
	_HURD_THREADVAR_RPC_VARS.
	* sysdeps/generic/bits/libc-tsd.h: Mention _LIBC_TSD_KEY_RPC_VARS.
	* include/rpc/rpc.h: Define data structures for internal thread-local
	"global" variables.
	Based on patches by Eric Norum <eric.norum@usask.ca>.
