4887dfcfd4 Stop libficl from using floating point registers - this was cauing
dictDelete() to fault early on the Alpha and was the original cause of
the Alpha ficl failures.

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)

0812b1e2c9 Fix world-breaking bug, add $FreeBSD$ tag.
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?

98c5378cdc Make FICL_TRACE default.
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.

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

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...

aa8b85772f Add conditional compilation facilities to ficl. This had been previously
committed to RELENG_3 instead of HEAD, so let's HEAD catch up.

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).

c82de3cb3f Add words "pc!" and "pc@" which allow to manipulate I/O ports. This can
be helpful when directly fiddling with PC hardware.

Also, define "arch-i386" appropriately, as suggested by Daniel C. Sobral.

8f1e6e6e22 Add support for some FACILITY words:
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...

37869e957d o Add proper stack checking to all file words
o add fkey and fread
o eliminate fexists now that this can be expressed in HLL forth
  ( : fexists fopen dup -1 <> if fclose 1 else drop 0 then ; ) :-)

Once we get the ability to write files, it should be possible to do
stand-alone rescue work from the 3rd stage boot. :)

82f35547c9 Remember a bit more of my forth and do:
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).
