New version that handles hardware flow-control (CRTSCTS) at the input
...
to the ring (or silo). This eliminates ring overrun with crtscts.
Also handle deferred register changes earlier, and misc. cleanup.

Make the ring size configurable in the tty driver.
...
Make the pseudo-interrupt functions return void.
Call the tty layer at spltty (to be safe).

New device attachment scheme:
...
- split softc size and match/attach out from cfdriver into
a new struct cfattach.
- new "attach" directive for files.*. May specify the name of
the cfattach structure, so that devices may be easily attached
to parents with different autoconfiguration semantics.
