5aef48a16b Add -mpreferred-stack-boundary=2 to CFLAGS for i386. This and libstand
reduces /boot/loader from 163840 bytes to 155648 and pxeboot from 165888
bytes to 157696 bytes.

70e1899762 Fix REFILL. It must throw RESTART instead of OUTOFTEXT so that
execution can take place at the point where it stopped after the
input buffer has been refilled.

Add ANS Forth CORE EXT and FILE word SOURCE-ID.

23bab6002c Make abort" functional in interpret mode. This behavior is undefined
by ANS Forth standard, but it's useful.

Also, define the constant true in a more strict way. C might garantee
2-complement math, but Forth doesn't.

8967d5f42e Improve on ficl port to alpha.
Files sysdep.[ch] are now in ${MACHINE_ARCH} subdirectory. Internal
#if's used to identify the platform where removed.

Make rule for target testmain was greatly simplified, because it was
easier simplifying it than changing it to support the new location of
sysdep.[ch].

(a repo-copy was done on sysdep.[ch], of course)

099d325dd5 Make ficlExec recursive. This removes vmReset and vmQuit from the

did, except what did shouldn't be doing, and might do a little more

15369f7e9f Fix ficlExecFD to take kern/9412 changes into account. Also modify it
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).

7505875a0a 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...

e9583ef187 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.

f7f7a5d7ab 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).

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...

780ebb4b00 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.

Ficl is distributed with the following license conditions:

"Ficl is freeware.  Use it in any way that you like, with the understanding
 that the code is not supported."
