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.

2fec81a60f Make ficl work on sparc64. The assumption that int == long == void * is
very pervasive in this code.  This fixes a few of those assumptions and
band-aids over some others.

Tested on: ia32 alpha sparc64

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.

rather commit and remove any uglyness later than hide it on my tree.

028fe6b9d1 The previous fix for "type" was absolutely lousy. Not only the buffer
allocated was not big enough, but it ended up to being used where it
was supposed to be used. The person who did that ought to be shot, but
since I'm a good person, I'll forgive myself...

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.

2aa626e3ff From the PR:
FICL's TYPE copies the counted string to HERE, as abial has
remarked. Answering to abial's question, this is NOT garanteed to have
enough space.
...
	We have dynamic memory. Even before memory-alloc got in, we
already had dynamic memory. Use it, then! (ficlMalloc is sysdep, so I
suppose that's why it was not used for TYPE; ficl is probably designed
to work without a working ficlFree).

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

key? ( -- flag)  \ check to see if there's a key to be read from input
ms   ( u -- )    \ wait that many milliseconds
seconds ( -- u ) \ get number of seconds from midnight.

'words' now outputs the list page by page - this probably should go
through libstand's pager, but will have to wait for closer integration of
built-ins with Forth...

  post-coldload initialization (in the default implementation, we
  look for /boot/boot.4th and load it if found).

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.
