offload MMIO accesses to KVM.

When the ' (tick) or postpone commands hit an unknown function, they simply
printed out "undefined word" without telling which word was not defined. These
problems were quite cumbersome to debug since it was quite hard to find the
right spot in the source code where such problems happened. Now the tick and
postpone command store the name of the undefined word, too, so that the code
which catches the ABORT also prints this information.
I also fixed the $FIND command to be standard compliant right from the start
(so that it leaves the string parameters on the stack in case the word has
not been found).

According to IEEE 1275, the "pack" command converts a Forth string into a
packed counted string, i.e. it has to store the length of the string in the
destination memory buffer, too, so that the operation can be reverted with the
"count" command. Our current implementation did not save the length yet - this
has been fixed now.
