Allow tty drivers to request larger buffers at attach time using a

max-baud-rate hint.  Adjust TTYHOG (the nearly full logic) to this new
situation.  The larger buffers are required by the very high speed
KDDI devices in Japan (CF com, or USB ucom) so those are the only two
drivers which currently ask for a larger buffer size.
