Various functions are only used within the sunrpc module, and several
are only use in the one file.  So clean up:

These are marked static, and any EXPORT is removed.
  svc_rcpb_setup()
  svc_rqst_alloc()
  svc_rqst_free()  - also moved before first use
  svc_rpcbind_set_version()
  svc_drop() - also moved to svc.c

These are now not EXPORTed, but are not static.
  svc_authenticate()
  svc_sock_update_bufs()
