Modified Files:
        src/sys/dev/ic: pckbc.c pckbcvar.h

Log Message:
In parallel to the interrupt handler pckbcintr provide two functions
pckbcintr_hard and pckbcintr_soft, which, together, do the same as
pckbcintr. The first is called from the interrupt handler, the second
from a softinterrupt at arbitrary protection level (lower or equal to
IPL_TTY). They pass data via a small ringbuffer.

The new functions are intended for platforms that, due to
hardware/firmware restrictions are not able to make pckbcintr called at
IPL_TTY, like Krups javastations. Using the monolithic pckbcintr on
these plattforms leads to the input handlers for the slot data to be
run at elevated priority, causing various race conditions.
