	(BRACK): Use more precise method for initialization.
	* Regenerate.
	* (dtable::stdio_init): Use get_cttyp instead of get_tty.
	(dtable::find_archetype): Use new DWORD operator in device to test archetypes.
	(dtable::init_std_file_from_handle): Use different method to initialize 'dev'.
	Adapt to different ctty handling and accommodate /dev/cons*.
	(fh_alloc): Accommodate no-longer-anonymous union.  Adapt to new /dev/cons*.
	(build_fh_pc): Make debugging output more useful.
	* (ctrl_c_handler): Use get_cttyp instead of get_tty.
	* (fillout_pinfo): Accommodate new cons* stuff.
	* (fhandler_base::read): Eliminate is_slow() test.
	* fhandler.h (fhandler_base::*): Adapt to changes in device.h.
	(fhandler_*::is_slow): Delete.
	( fhandler_proc::get_proc_fhandler): Return fh_devices type.
	* (open_shared_console): New function.
	(console_unit): New class.
	(console_unit::console_unit): New constructor.
	(enum_windows): New function.  Declare as friend to console_unit.
	(fhandler_console::set_unit): New function.
	(fhandler_console::get_tty_stuff): Call set_unit to set the unit number and
	determine if initialization is needed.  Eliminate flags parameter.
	(tty_list::get_cttyp): Rename (sorta) from get_tty.  Return pointer to correct
	(fhandler_console::open): Adapt to elimination of argument to get_tty_stuff.
	(fhandler_console::output_tcsetattr): Properly detect error condition.
	(fhandler_console::fixup_after_fork_exec): Adapt to get_tty_stuff() setting tc
	* Use FH_BAD rather than 0 throughout where using fh_devices
	(fhandler_proc::get_proc_fhandler): Return fh_devices.  Adapt to devices.h
	* Adapt to devices.h changes.  Use FH_BAD rather than 0
	throughout where using fh_devices enum.
	* Ditto.
	* Ditto.
	* Ditto.
	* (fhandler_dev_tape::fhandler_dev_tape): Ditto.
	* (handler_termios::bg_check): Use tc->ttyname() rather
	than assuming that we can construct a tty.
	* (fhandler_tty_master::fhandler_tty_master): Just return
	get_minor() of dev.
	(fhandler_pty_master::process_slave_output): Add slightly more debugging info.
	(fhandler_tty_slave::fhandler_tty_slave): Change name from ntty to unit.
	(fhandler_pty_master::open): Ditto.
	(fhandler_tty_slave::ioctl): Adapt to change which causes ctty to represent a
	complete device.

	(mount_info::conv_to_win32_path): Ditto.
	* (path_conv::check): Retrive major/minor numbers via a method rather
	than accessing them directly from device.  Rely on dev operators to
	set/retrieve device information as required by device struct change.
	* path.h (isproc_dev): Move to devices.h.
	(isprocsys_dev): Ditto.
	(isvirtual_dev): Ditto.
	Use device methods to access/manipulate devices.
	* (pinfo::exit): Don't assume that ctty == 0 is valid.  Use iscons_dev
	to determine if a device is a console.
	(_pinfo::_ctty): Use device::parse to generate tty/cons name.
	(_pinfo::set_ctty): Don't assume that ctty == 0 is valid.  Remove redundant
	info from debugging.
	* (offsets): Remove console offset.

	* (umask): Use device methods to manipulate device information.
	(ctermid): Use device::parse to generate term device name.
	* tlsoffsets.h: Regenerate.
	* (ttyslot): Return minor number of ctty since ctty now represents a
	full device.
	(tty::create_master): Set ctty to a complete device.
	(tty_list::attach): Rework to detect new /dev/cons* stuff.
	(tty_list::terminate): Adapt to changes to ctty.
	(tty_list::init): Adapt to change to setntty - pass in device major number.
	(tty::exists): Use get_unit() to retrive tty unit number.
	(tty::open_mutex): Ditto.
	(tty::open_inuse): Ditto.
	(tty::create_inuse): Ditto.
	(tty::get_event): Ditto.

	(tty::exists): Use get_unit() to retrive tty unit number.
	(tty::open_mutex): Ditto.
	(tty::open_inuse): Ditto.
	(tty::create_inuse): Ditto.
	(tty::get_event): Ditto.
	(tty_min::ttyname): Declare new function.
	(tty::getntty): Declare as const.

	* (dll_list::alloc): Detect mismatch of data segments early issuing
	an explicit error message if necessary.
	* (heap_init): Adapt to changes from fork->handle_failure to
	* pinfo.h (EXITCODE_FORK_FAILED): New enum.  (from Ryan Johnson)
	* (child_info_fork::abort): Rename from handle_failure.  Change
	arguments to allow passing in a printf-like message.

	(api_fatal): Redefine from __api_fatal.
	(vapi_fatal): Declare new function.
	* include/sys/strace.h (strace_vprintf): Define new macro.
