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.
This happened to be my first "for real" broken world. I had broken
it once before, but nobody noticed, so it didn't count.
So, how do I get the "I broke world and all I got was the lousy t-shirt"
t-shirt?
Add freebsd.fr, for FreeBSD specific forth source. Add $ and %, to
replace the lost @ and - functionality of include. $ has the opposite
behavior of @ though, since the default behavior was inverted.
Make TIB handling use buffer size to conform with ANS Forth.
Add ANS MEMORY-ALLOC word set.

needs. This removes the dependancy on Perl for the generation of the
loader, allowing the world to be built on a perl-free system.

o Add fexists word to check for the presence of a file
o make fexists and fload immediate words which DTRT both interpreted
and compiled (doh!)
o add an init word which gets run at bootstrapping time to do extra
post-coldload initialization (in the default implementation, we
look for /boot/boot.4th and load it if found).
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.
