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.

d742bdfc76 The word environment? returns a flag indicating whether the variable 
was found or not. Fix it's usage. Alas, it caused no problem before,
besides leaving garbage in the stack, because refill, used by [if]
[else] [then], was broken.

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.

c1312289dd Modify boot-conf so it can take a kernel or directory name as 
a parameter and dtrt.

Also, make boot-conf always unload first. There wasn't really any
point in not doing this, as the kernel _has_ to be loaded before
any other modules.

638bac9fc0 Clean up all of the 16-bit assembly code in the x86 bootstrap to work 
with the new binutils.  Now that we have a decent assembler, all the old
m4 macros are no longer needed.  Instead, straight assembly can be used
since as(1) now understands 16-bit addressing, branches, etc.  Also,
several bugs have been fixed in as(1), allowing boot0.s to be further
cleaned up.

7f562b6673 The loader was written so that if /kernel was missing /kernel.old would 
be booted.  Due to a bug, this wasn't happening.

There is still a lesser bug in that the loader decides which file to boot
after the 10sec count down.  This means the bootfile listed in the count
down in is wrong in the case where the loader will boot /kernel.old.

dafe1ac0a0 Reactivate the FICL hooks to make it be compiled in, but also initialize 
FICL.  bootforth is now live on the Alpha!

**BEWARE** - you *MUST* build and install a current libstand or you will
most likely get zfree() panics at loader startup.

We should now be able to set up the loader.conf stuff on the Alpha too.

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.

fa139a1ac3 Fix the Alpha loader the rest of the way. If FICL is present in 
/boot/loader (even though it is 100% dormant in the Alpha version),
then the loader panics with a zfree error:Loading /boot/loader.test
  *** keyboard not plugged in...
  Console: SRM firmware console
  panic: zfree(0x2003cb58,4096): wild pointer
versus the exact same code but without FICL linked in:
  Loading /boot/loader

  VMS PAL rev: 0x1000600010114
  OSF PAL rev: 0x1000600020116
  Switch to OSF PAL code succeeded.

  FreeBSD/alpha SRM disk boot, Revision 0.1

This is almost certainly an alpha infrastructure bug, not a FICL
problem.  It's probably the same thing that made FICL fail for no
apparent reason on the Alpha.

325bde0fb7 Remove metion of the 'magic options.' Apparently PXE doesn't require the 
special options on 0.99c (it mumbles something about 'PXE server not found'
but works anyway), and it won't work at all with PXE 2.0.

773065b3b8 Switch to using the .code16 as(1) directive and using 16-bit assembly 
code instead of using 32-bit code and having to just "know" that it's
really 16-bit instructions when things run.  This also allows the code
to use fewer macros and more actual assembly statements, which eases
maintenance.  Unfortunately, due to as(1) brokenness, we still use m4
macros for all 16-bit addresses, and all short jumps (i.e., 8-bit
relative addresses in the jump instruction) must be wrapped in .code32
directives to avoid useless bloat by as(1).  This also fixes a few
problems that were preventing boot0 from compiling with the latest
and greatest version of as(1).
