ACPI panic on boot with new Lua loader and other minor issues

I have done a full build of r329555 to test the new Lua boot loader.

Both the new and the old kernels panic after being loaded with:

panic: running without device atpic requires a local APIC

For reasons unknown, ACPI is off, as shown by David Wolfskill in a 
previous message:
https://lists.freebsd.org/pipermail/freebsd-current/2018-February/068497.html

OK show hint.acpi.0.disabled
1

Setting ACPI to On resolves the issue.

Also, I can not stop boot2 to try to use the copy of the Forth loader: 
the keyboard only becomes responsive at the loader stage.

There is an error during this stage:

Loading /boot/defaults/loader.conf
Failed to open config: ’/boot/loader.conf.local’

Moreover, the "boot [kernel]" loader command does not work:

OK ls /boot/kernel.old/kernel
     /boot/kernel.old/kernel
OK boot kernel.old
Command failed
OK boot /boot/kernel.old/kernel
Command failed
OK boot kernel
Command failed

On the other hand, just "boot" works.

Finally, the double lines drawing a frame around the loader menu do not 
work with the new loader and are replaced by ? characters in a box.

Hope it helps,
Juan
