Bump up the heap size to 1MB. With a few kernel modules, libstand
zalloc and userboot seem to want to use ~600KB of heap space, which
results in a segfault when malloc fails in bhyveload.
r241180
Clarify comment about default number of FICL dictionary cells.
r241153
Allow the number of FICL dictionary cells to be overridden.
Loading a 7.3 ISO with userboot/amd64 takes up 10035 cells,
overflowing the long-standing default of 10000.
Bump userboot's value up to 15000 cells.

command execution. In case of such unhandled exception, vmReset() inside
ficlExecC() flushes the VM state. Attempt to return back to Forth after
that cause garbage dereference with unexpected results. To avoid that
situation call vmThrow() directly instead of expecting Forth to do it.
On OFW based machines, it is just too confusing having the firmware and
OS loader giving the same prompt. This is a nice compromise that 99% of the
users on non-OFW platforms will probably not even notice.
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.
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.

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).

as Forth words, and handle them being called from there.
