* exceptions.cc (signal_exit): Reset all mutos owned by the main thread.

Browse Source 
* fhandler.h: Define *_output_mutex macros for serializing tty output.
(fhandler_termios): Remove restart_output_event.  Define dummy output mutex
methods.
(fhandler_pty_master): Remove unneeded fixup_after_fork method.
* fhandler_termios.cc (fhandler_termios::line_edit): Acquire output_mutex when
CTRL-S is hit.  Release it on CTRL-Q.
* fhandler_tty.cc (fhandler_pty_master::process_slave_output): Remove
inappropriate OutputStopped test here.  Just use the output mutex.
(fhandler_pty_master::fhandler_pty_master): Remove obsolete reference to
restart_output_event.
(fhandler_tty_common::close): Ditto.
(fhandler_pty_master::set_close_on_exec): Ditto.
(fhandler_pty_master::fixup_after_fork): Delete.
* tty.cc (tty::common_init): Ditto.
