	cygwin         : ChangeLog dcrt0.cc exceptions.cc 
	                 fhandler_console.cc fhandler_termios.cc 
	                 fhandler_tty.cc pinfo.cc tty.cc tty.h 

Log message:
	* dcrt0.cc (dll_crt0_0): Call tty_list::init_session here.
	(dll_crt0_1): Reflect renaming from tty_init to tty::init_session.
	(do_exit): Reflect moving of tty_terminate into tty_list.
	* exceptions.cc (events_init): Move tty_mutex stuff elsewhere.
	* fhandler_console.cc (set_console_title): Use lock_ttys class.
	* fhandler_termios.cc (fhandler_termios::bg_check): Make debug output more
	accurate.
	* fhandler_tty.cc (fhandler_tty_slave::open): Reflect move of attach_tty into
	tty_list class.  Don't attempt to grab master end of pty if master doesn't
	exist.
	(fhandler_pty_master::open): Reflect move of allocate_tty into tty_list class.
	Use lock_ttys::release to release mutex.  Improve debugging output.
	(fhandler_pty_master::setup): Remove if 0'ed block.  Fix argument to
	SetNamedPipeHandleState.
	* pinfo.cc (_pinfo::set_ctty): Lock ttys before setting sid/pgid.  Improve
	debugging.  Add temporary debugging.
	* tty.cc (tty_list::init_session): New function.
	(tty::init_session): Rename from tty_init.  Reflect move of attach_tty to
	tty_list class.
	(tty::create_master): Rename from create_tty_master.
	(tty_list::attach): Rename from attach_tty.  Reflect renaming of connect_tty to
	connect.  Ditto for allocate_tty.
	(tty_terminate): Delete.
	(tty_list::terminate): Subsume tty_terminate.  Use lock_ttys rather than
	manipulating mutex directly.
	(tty_list::allocate): Rename from allocate_tty.  Use lock_ttys rather than
	manipulating mutex directly.  Don't set sid here since linux apparently doesn't
	do this.  Reflect move of create_tty_master into tty.
	(lock_ttys::lock_ttys): Define new constructor.
	(lock_ttys::release): New function.
	* tty.h (tty::exists): Return false immediately if !master_pid.
	(tty::set_master_closed): Define new function.
	(tty::create_master): Ditto.
	(tty::init_session): Ditto.
	(tty_list::mutex): New field.
	(tty_list::allocate): Define new function.
	(tty_list::connect): Ditto.
	(tty_list::attach): Ditto.
	(tty_list::init_session): Ditto.
	(lock_ttys): New class.
	(tty_init): Delete declaration.
	(tty_terminate): Ditto.
	(attach_tty): Ditto.
	(create_tty_master): Ditto.
