Clean up license text

- Renumber Regents clauses
- Remove clause 3 and 4 from TNF license, following upstream change

Convert files to UTF-8

- Define data of struct gfb_font a const as it's only used to supply font
data and remove the array size from the definition as f.e. the gallant
12 x 22 font data is 256 * 44 in size, exceeding the previously hard-
coded size.
- Declare the bold8x16 instance of struct gfb_font as const as it's not
intended to be changed at run-time as a whole either.
- Use __FBSDID in xboxfb.c

- Garbage collect more alpha remnants.
- Fix a typo in a comment in boot_font.c.

Since DELAY() was moved, most <machine/clock.h> #includes have been
unnecessary.

Remove unecessary include file. machine/rpb.h is very alpha specific
and is not needed for this font, which isn't alpha speciifc.

Remove bus_{mem,p}io.h and related code for a micro-optimization on i386
and amd64. The optimization is a trivial on recent machines.

- Remove duplicate FBSDID.
- Start copyright comments with /*- where missing.

Use __FBSDID().
Also some minor style cleanups.

Prefer new location of pci include files (which have only been in the
tree for two or more years now), except in a few places where there's
code to be compatible with older versions of FreeBSD.

Add the TGA video driver. This is a great accomplishtment and will help
us a lot on older Alphas.
