to tell driver to probe/not probe the device for IRQs.
This incorporates most of Bruce's review material. I'm at a good
checkpoint, but there will be more to come based on bde's further
reviews.

Move sio from isa/sio.c to dev/sio/sio.c. The next step is to break
out the front end attachments, improve support for these parts on
different busses, and maybe, if we're lucky, merging in pc98 support.

- Count the number of this error.
- When the error is detected for the first time, the psm driver will
throw few data bytes (up to entire packet size) and see if it can
get back to sync.
- If the error still persists, the psm driver disable/enable the mouse
and see if it works.
- If the error still persists and the count goes up to 20,
the psm driver reset and reinitialize the mouse. The counter
is reset to zero.
- It also discards an incomplete data packet when the interval
between two consequtive bytes are longer than pre-defined timeout
(2 seconds). The last byte which arrived late will be regarded as
the first byte of a new packet. This is louie's idea.
You may see the following error logs during the above operations:
"psmintr: delay too long; resetting byte count"
"psmintr: out of sync (%04x != %04x)"
"psmintr: discard a byte (%d)"
"psmintr: re-enable the mouse"
"psmintr: reset the mouse"

- crhold() returns a reference to the ucred whose refcount it bumps.
- crcopy() now simply copies the credentials from one credential to
another and has no return value.
- a new crshared() primitive is added which returns true if a ucred's
refcount is > 1 and false (0) otherwise.
