serial lirc driver for testing (and a book review)

[Juergen Lock]

I have now updated the shar and patch to uart(4) code from head
(instead of 9.0), fixed read() not respecting O_NONBLOCK, and improved
behaviour at kldunload:

and

	http://people.freebsd.org/~nox/tmp/uartlirc-preliminary-002.shar

If someone would like to comment on the code I'd be grateful! :)
