Joerg Wunsch 15c99149f8 Boot block cleanup.
o Fix the keyboard probe to properly wait for the ready bit before
sending a command to the keyboard controller.  This should avoid the
problems some people are experiencing where the boot blocks hang the
system during keyboard probe.  (It does solve it for me.)

o Fix a bug that effectively prevented the boot blocks from ever
passing control to the serial console.  [while(--retries) instead of
while(retries--)]

o Gratuitously reduced the keyboard probe timeout from 500 to 5
seconds. :)

o Introduced a new option ``FORCE_COMCONSOLE'' as a commented-out
example in the Makefile, to force the usage of a serial console
regardless of a keyboard being connected or not.

o Moved all external declarations to boot.h, declared all functions
there, and ANSIfied all function declarations/definitions.
(printf() remains bogus, however -- i'm too lazy to fix this.)
We're in the ninetees, dunno why we should still support compilers
from the 70's.
