* process.c: Make symbols static if they're not exported.

(process_tick, update_tick, create_process, chan_process):
(Vprocess_alist, proc_buffered_char, datagram_access):
(fd_callback_data, send_process_frame, process_sent_to): Now static.
(deactivate_process): Mark defn as static, as well as decl.
* lisp.h (create_process): Remove decl.
* process.h (chan_process, Vprocess_alist): Remove decls.
