72ab07e9db 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.

60ace12c39 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.

90242e0822 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).

0fa743a353 The trace facility was full of bugs. Correct that by using the

028fe6b9d1 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...

0ebff7e4fd Add conditional compilation facilities to ficl. This had been previously
committed to RELENG_3 instead of HEAD, so let's HEAD catch up.

e106763b92 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.

2aa626e3ff 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).

488523664e Transition from using Perl to using awk for our text-manipulation

741d3b95c6 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.

25196ce9dd 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...

94f344ce1c 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. :)

33ecda9af6 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).

fe1c6b5af2 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."
