scw 54f42f17fc Don't bother spinning in the console 'putc' routine for the transmitter
to become idle; it actually doesn't matter as the chip takes care of
this for us. It would also spin endlessly in certain circumstances
during shutdown.

While I'm here, (finally) add code to allow sending BREAK characters.

scw ba922d31d8 Re-work the Tx side to avoid calling into the tty layer at

seen by several people, as the Tx interrupt is at a higher
priority that spltty().

scw 94719c7b9a New MI front-end for the Cirrus Logic CD240[01] Multi-protocol
Communications Controller.

This is still a work in progress, but it is functional enough to
be usable.
