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.
help.common
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.

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).
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).
