Fix and update for VESA BIOS support in syscons.

- Handle pixel (raster text) mode properly.
   - Clear screen and paint border right.
   - Paint text attribute (colors).
   - Fix off-by-one errors.
   - Add some sanity checks.
- Fix some function prototypes.
- Add some comment lines.
- Define generic text mode numbers so that the user can just give
  "80x25", "80x60", "132x25"..., rather than "VGA_xxx", to `vidcontrol'
  to change the current video mode.  `vidoio.c' and `vesa.c' will map
  these numbers to real video mode numbers appropriate and available
  with the given video hardware.  I believe this will be useful to make
  syscons more portable across archtectures.
