	* term.h: Include `hurd/hurd_types.h'.
	(struct bottomhalf): Change the return types of the following
	members from void to error_t: abandon_physical_output,
	suspend_physical_output, notice_input_flushed, desert_dtr,
	set_break, clear_break, start_output, set_bits (which now takes an
	struct termios * as argument), mdmctl and mdmstate (which now
	takes an int * as argument).  Add new members init and type.
	(bottom): Define as const.
	(devio_bottom, ptyio_bottom): Declare as const.
	(drop_output): Change return type from void to error_t.
	(ptyio_init): Remove prototype.
	* devio.c (devio_abandon_physical_output): Change return value to
	error_t, and return 0.
	(devio_suspend_physical_output): Likewise.
	(devio_notice_input_flushed): Likewise.
	(devio_desert_dtr): Likewise.
	(devio_set_break): Likewise.
	(devio_clear_break): Likewise.
	(devio_start_output): Likewise.
	(devio_set_bits): Likewise.
	(devio_mdmctl): Likewise.
	(devio_mdmstate): Likewise.
        (init_devio): Rename to ...
	(devio_init): ... this.  Do not give constructor attribute.
	Change return type to error_t, and return an error value, rather
	than bailing out.  Declare as static.
	(devio_bottom): Add type TERM_ON_MACHDEV and init function
	devio_init.
	(devio_set_bits): Accept new argument STATE and use that to work
	out the terminal state, rather than changing the global termstate.
	(devio_mdmstate): Accept new argument STATE and use that to return
	the bits.
	* ptyio.c: Do not include `hurd/hurd_types.h'.
	(ptyio_suspend_physical_output): Change return value to error_t,
	and return 0.  Likewise.
	(ptyio_notice_input_flushed): Likewise.
	(ptyio_desert_dtr): Likewise.
	(ptyio_set_bits): Likewise.
	(ptyio_set_break): Likewise.
	(ptyio_clear_break): Likewise.
	(ptyio_mdmctl): Likewise.
	(ptyio_start_output): Likewise.
	(ptyio_abandon_physical_output): Likewise.
	(ptyio_mdmstate): Likewise, and accept new argument STATE.
	(ptyio_init): Declare as static and change return type to error_t.
	(ptyio_bottom): Add type TERM_ON_MASTERPTY and init function
	ptyio_init.
	(ptyio_set_bits): Accept new argument STATE and use that to work
	out the terminal state, rather than changing the global termstate.
	(ptyio_mdmstate): Accept new argument STATE and use that to return
	the bits.
	* munge.c (drop_output): Change return value to error_t.  Only
	clear queue if there was no error.
	* users.c (S_term_get_bottom_type): Just return bottom->type.
	(set_state): Rework logic to take possible errors into account,
	and to delay changing the termstate until we know that we won't
	fail.
	(S_tioctl_tiocflush): Return errors properly, and clear queue only
	if notice_input_flushed succeeded.
	(open_hook): Save error value of set_bits.  Save old termflags and
	restore them if if set_bits failed.  Call set_bits with correct
	arguments.
	(S_tioctl_tiocmods): Set err to result of mdmctl.
	(S_tioctl_tiocmset): Likewise.
	(S_tioctl_tiocmbic): Likewise.
	(S_tioctl_tiocmbis): Likewise.
	(S_tioctl_tioccdtr): Likewise.
	(S_tioctl_tiocsdtr): Likewise.
	(S_tioctl_tioccbrk): Likewise for clear_break.
	(S_tioctl_tiocsbrk): Likewise for set_break.
	(S_tioctl_tiocstart): Likewise for start_output.  Save old
	termflags and restore them if if start_output failed.
	(S_tioctl_tiocstop): Likewise for stop_output.
	(S_trivfs_io_write): Abort the operation if start_output fails.
	Do not call start_output if it just failed, or if there was no
	data to be written.
	* main.c (main): Initialize bottom handler (rather than special
	casing this for ptyio).

	* users.c (open_hook): Use memcpy instead bcopy and memset instead
	bzero.
	(S_tioctl_tiocgeta): Likewise.
	(set_state): Likewise.
	(open_hook): Likewise.
	* munge.c (rescan_inputq): Likewise.
