As of this patchset, the loader builds (under NetBSD/macppc), boots, interacts
and talks to BOOTP/NFS servers.

gets the name from the environment variable kernelname, which is set
when a kernel is loaded. For this reason, autoboot will _first_ try
to load a kernel, and only proceed with the wait prompt after that
succeeds. If it fails, it will abort immediately.
While I understand some may think this behavior undesirable, I think
it is, overall, the best thing to do, even if we do not consider the
aesthetic issue. Notice that anyone using the default loader.rc
already has the kernel loaded before autoboot.
On unload, unset kernelname.
Separate the code that tries to load a kernel from the list of options
to the function loadakernel(). It is used by both boot() and
autoboot().

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.

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.

proposed root filesystem to determine the actual device name and vfs

via the environment variable vfs.root.mountfrom.
Use colons instead of semi-colons in the default init_path to behave like

* Make the network code in the bootstrap more chatty (helps debugging)
* Add nfs root stuff to cpu_rootconf(). I also added a check to make sure
it really was netbooting which allows the use of the same kernel for local
and network boots.
* Tweak the de driver so that it takes the speed setting from the console

behaviour as NetBSD/alpha.

i386 platform boots, it is no longer ISA-centric, and is fully dynamic.
Most old drivers compile and run without modification via 'compatability
shims' to enable a smoother transition. eisa, isapnp and pccard* are
not yet using the new resource manager. Once fully converted, all drivers
will be loadable, including PCI and ISA.
(Some other changes appear to have snuck in, including a port of Soren's
ATA driver to the Alpha. Soren, back this out if you need to.)
This is a checkpoint of work-in-progress, but is quite functional.

Also, unbreak the breakage introduced at the last revision of module.c.
This changes the semantics of mod_searchfile() (and mod_searchmodule())
to make the caller's responsibility freeing the buffer returned. This
is different from other functions in loader's code, and was done as a
fix for kern/9631. If someone wants to revert this to the original
behavior, don't forget to fix kern/9631 in another way.
This should also fix bin/10462, which was introduced as a result of the
first try at kern/9631 (module.c last revision).

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.
