e165b852de Cleanup warnings. Most of these are signed/unsigned warnings, as well as
some added const's.

a916ed2bd7 Fix vocabulary juggling so that builtins voc is always searched before
forth vocabulary when initially creating the builtins. FICL 2.05 has a
better way to do this, but this works for now.

Fixes "?".

cb251cf529 Remove the setting of sourceid from bf_vm(), as bf_vm() really has
no clue.

Set sourceid to 0 when booting, which is the correct setting for stdin.

Set sourceid to an arbitrary fd when include'ing, preserving and restoring
the previous sourceid. This is possibly broken(), as 0 is a valid fd. Maybe
we should +1 to this value.

This fixes the version problem widely reported.

cf59a85113 Place original builtins in a vocabulary called "builtins". This
is intended mainly for debuging purposes, but it can be used by
other words if done carefully.

755c131c9f Make use of prototypes to silence warnings.
Change include() so it will be able to load files with forth code,
instead of just builtins. Remove #@- from the include section of the
help file, since they don't work in the new version of include, unless
BOOT_FORTH is not defined.

Change bf_run() so it will return the result returned by ficlExec(). Also,
make bf_run() push "interpret" to be executed by ficlExec(), since ficlExec()
doesn't do it by itself. (Things worked previously because nothing
recursed through ficlExec() by the way of bf_run()).

Change/extend comments on builtin behavior.

Search for "interpret" at the end of bf_init(), so /boot/boot.4th can
provide it's own version.

Remove dead code.

interp.c
	Rename the 'source' command to 'include' in order to avoid conflict
	with the ANS Forth command of the same name. (kern/9473)

interp_forth.c:
	Changes from kern/9412 (EXCEPTION word), kern/9442 (TIB buffer
	sizing) and an improved version of kern/9460 (set
	version numbers).

load_aout.c:
	Trim some obsolete #if 0'ed cruft.

pnp.c:
	Tidy the pnpscan output, turn off the module scanning until we
	sort out how to do it right.

524f060924 * Begin integration of built-ins with Forth: leave the exit code from
a built-in command on Forth stack.
* Fix a bug which was causing a panic when loading stripped aout kernels.

0ba901f49f Eliminate much code cruft by extending simple file I/O API to include
fopen and fclose.  Also look for /boot/boot.4th now and, if found,
load its contents.

8602321e78 Don't use the poxy vmGetString interface (who uses counted strings these
days?), get the input buffer ourselves.  Add some debugging code.

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).

155c4cb295 Add BootForth hooks; if BOOT_FORTH is defined, pass every line read
to the Forth interpreter.  Instantiate all of our inbuilt commands
as Forth words, and handle them being called from there.

Add my copyright to the bcache module (oops).
