15369f7e9f Fix ficlExecFD to take kern/9412 changes into account. Also modify it
not to vmThrow errors. This is not what the comments say it does, and
it doesn't work when there is no ficlExec environment (like it's only
use in sys/boot/common/interp_forth.c).

e08e812d7a The trace facility was full of bugs. Correct that by using the
right variable.

e9583ef187 From the PR:
I added a FICL_TRACE-conditioned trace facility based on "see".
It is ugly because words' functions are almost all static, and ficlExec,
where the trace has to be located, can't get their pointers. So, #ifdef
this staticization, and add most of see's body into ficlExec. Duplication
of code, uglyness, etc. But it is cleanly #ifdef'ed, and works like a
charm.

	It does not provide "step" facility, though, just trace. It is
tunable at run-time through "trace!". If anyone (most likely me :) ever
wants a step facility, I'll add it. Should be easy.

8190a019a5 Don't not print the prompt string; not doing this has funny side-effects.
Make the prompt an empty string instead.

4ce140ae69 Fix includes; we were still pulling in <stdlib.h> in some places.
Support building a standalone interpreter with 'make testmain', remove
win32 and egregious gets() in testmain.c

780ebb4b00 Add the Ficl (Forth Inspired Command Language) interpreter. If all goes well,
this will allow us to manage bloat in the loader by using a bytecoded HLL
rather than lots of C code.  It also offers an opportunity for vendors
or others with special applications to significantly customise the boot
process without having to commit to a divergent code branch.

This early commit is to allow others to experiment with the most effective
mechanisms for integrating FICL with the loader as it currently stands.

Ficl is distributed with the following license conditions:

"Ficl is freeware.  Use it in any way that you like, with the understanding
 that the code is not supported."
