GCC 4.8 build fixes from John D. Baker

Put a missing newline.

Remove clause 3 and 4 from TNF licenses

General fixups:
1) Fix support for the powerstack E1. This machine needs to use the 8259
directly, and cannot use the prep interrupt vector register. Place a
quirk entry in the table for the machine.
2) Add a new com0_vreset boot image. The vreset code only works on a few
machines, and breaks others like the 7025-F40. Its only limitedly useful
when used with the com0, so just make it an optional image the user can
install by hand if they want.
3) Bump the bootloader to 1.8 with the above change.

More major bootblock changes:
1) Rewrite vreset.c completely. Saves about 1k, and now it sets the
screen up much better. Previously the resulting video mode looked bad on
my CRT, and my LCD wouldn't even recognize it as a valid mode. Now it
looks reasonably good and my LCD can talk to it.

2) Call vga_reset unconditionally in the setup process to fix the onboard
VGA. If you have a VGA and use the serial console, this will allow you
to still use the VGA device for getty/wscons. Tested on a 7248 with VGA
and a 7043 without VGA.

3) Change filesystem.c to use nullfs rather than ufs and cd9660. We
don't actually need an fs at all, but it would take a major rewrite to
get rid of them completely. This saves about 6KB on the bootloader.

4) Bump version to 1.7.
