establishing the carrier.

* ptyio.c (pty_io_readable): int -> size_t in argument type.
* term.h: Update decl.
* users.c (trivfs_S_io_write): int -> size_t in AMT argument type.
(trivfs_S_io_readable): Likewise.

* main.c (main): Use memset instead bzero.
Fix error message, and formatting of some comments.
* ptyio.c (pty_io_read): Use memcpy instead bcopy.
* users.c (S_tioctl_tiocflush): Ignore error by bottom handler's
notice_input_flushed.
* users.c (set_state): Likewise.
If bottom handler's set_bits fails, don't adjust terminal state
but return success anyway.

* 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.
