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.
error cases, but the replacement should be doing everything they
did, except what did shouldn't be doing, and might do a little more
they ought to be doing.
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).

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.

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.
