(deactivate_process, status_notify, read_process_output)

(update_status, status_convert, decode_status, allocate_pty)
(make_process, remove_process, list_processes_1)
(create_process_1, unwind_request_sigio, read_process_output)
(send_process, keyboard_bit_set): Declare static.
(Fdelete_process): Simplify.  Pass process to status_notify, so we
don't try to read output from it.
(status_notify): New arg deleting_process--don't try to read
output from that process.
