(list_processes_1): Remove unused variables.

(Fopen_network_stream, create_process): Add parentheses to
conditional expressions.
(create_process): Put declaration of sigchld in #if 0.
(Fopen_network_stream): Removed unused variables.
(Fopen_network_stream, wait_reading_process_input,
wait_reading_process_input, send_process, send_process): Ditto.
(toplevel): Add prototypes for set_waiting_for_input and
keyboard_bit_set.
