Avoid race for the chip's interrupt pending status bits in zscnputc()

by introducing a single-character queue to defer kernel console output
until the transmitter interrupt handler runs.

as per discussion with torek, allow TC=1. also add option
...
to allow TC=0. the zilog documentation says not to allow
TC=0 -- however, i tested this and it "does work", as far
as i could tell, so, allow this use if so desired.

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.

Extend the size of the "soft" FIFOs which reportedly reduces the number
...
of FIFO overflows on high baud rates.
However, doing so on all 4 ports would cost a whopping 64KB (at 4096 entries
per FIFO) of kernel memory. So, the FIFOs are now allocated at attach time
allowing the size for the keyboard and mouse ports to be reduced (to 128)
which should be adequate for the 1200 baud they use.
