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.

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.
