9005b02e0e Extend `autoboot_delay' handling - is this variable is set to -1 don't allow
user to interrupt autoboot process at all. Currently, even when
`autoboot_delay' is set to 0, loader(8) still allows autoboot process to be
interrupted by pressing any key on the console when the loader reads kernel
and modules from the disk. In some cases (i.e. untrusted environment) such
behaviour is highly indesirable and user should not be allowed to interfere
with the autoboot process at all.

4141c80005 remove /boot/kernel from the default path.. There is already code that
will prepend the current kernel booting...  This prevents a problem of
loading /boot/kernel's modules when a different kernel has no modules,
but you left your module_load="YES" in loader.conf...

8b1373b33e Rename the kern.vm.kmem.size tunable to the more logical vm.kmem_size. To
assure backward compatibility (conditional on !BURN_BRIDGES), look it up
by its old name first, and log a warning (but accept the setting) if it
was found.  If both the old and new name are defined, the new name takes
precedence.

Also export vm.kmem_size as a read-only sysctl variable; I find it hard to
tune a parameter when I don't know its default value, especially when that
default value is computed at boot time.

087c82acdb Some more i386-only BIOS-friendliness:
- Add support for using the PCI BIOS functions for configuration space
   accesses, and make this the default.

 - Make PNPBIOS the default (obsoletes the PNPBIOS config option).

 - Add two new boot-time tunables to disable each of the above.

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.
