Fix 2010-05-05T22:14:15Z!lekktu@gmail.com.

 keyboard.c (kbd_buffer_nr_stored): Define only ifdef subprocesses.
 (kbd_buffer_store_event_hold, kbd_buffer_get_event)
 (tty_read_avail_input): Call kbd_buffer_nr_stored only ifdef
 subprocesses.  Use buffer_free only ifdef subprocesses.
 process.c (init_process) [subprocesses]: Init kbd_is_on_hold in
 the subprocesses version, not in the non-subprocesses one.
