* exceptions.cc (ctrl_c_handler): Send SIGHUP when events occur only if there

is a tty associated with the process.  Send SIGHUP on CTRL_LOGOFF_EVENT.
* fhandler_tty.cc (fhandler_tty_slave::open): Adjust console open handle
counter regardless of whether this is a pty or tty.
(fhandler_tty_slave::open): Ditto.
(fhandler_tty_slave::dup): Ditto.
(fhandler_tty_common::set_close_on_exec): Ditto.
(fhandler_tty_master::init_console): Decrement console open handle counter
after init since it will now be handled by all tty open.
* syscalls.cc (setsid): Rework debugging output slightly.
