ade9ba91cb Update to FICL 3.03 (the last release before FICL4 rewrite).
The relevant changes for FreeBSD (excerpt from the release note):

  * Newly implemented CORE EXT words: CASE, OF, ENDOF, and ENDCASE. Also
    added FALLTHROUGH, which works like ENDOF but jumps to the instruction
    just after the next OF.
  * Bugfix: John-Hopkins locals syntax now accepts | and -- in the comment
    (between the first -- and the }.)
  * Bugfix: Changed vmGetWord0() to make Purify happier. The resulting
    code is no slower, no larger, and slightly more robust.

5dc04c92e8 Instead of just not defining a bunch of words when TESTMAIN is set, provide
stubs that at least handle the stack correctly.  This makes it much easier to
experiment with loader scripts from userland.

eeb34873c0 Upgrade to FICL version 3.02. Anything wrong is my fault, everything right is

fa71f8751f Turn dictthreshold and dictincrease into cell-sized variables, so
they can be used with cell operators like !.

As I did this, I noticed the whole CELL thing might have problems with
big endian architectures with sizeof(int)!=sizeof(void*).

1e7d7fa081 Bring in ficl 2.05.
This version has a step debugger, which now completely replaces the
old trace feature. Also, we moved all of the FreeBSD-specific MI
code to loader.c, reducing the diff between this and the official
FICL distribution.

e8604ccc3e Add the infrastructure necessary to handle PnP from a Forth script.
Also, export the file_findfile() function. Again, this is taken from
work in progress but frozen for the time being. Since it works, I'd
rather commit and remove any uglyness later than hide it on my tree.

e106763b92 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.

741d3b95c6 Add words "pc!" and "pc@" which allow to manipulate I/O ports. This can
be helpful when directly fiddling with PC hardware.

Also, define "arch-i386" appropriately, as suggested by Daniel C. Sobral.

fe1c6b5af2 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.
