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.
