aca7ff54b0 [BOOTVID] Correctly fix scrolling and printing when the scroll region contains the whole screen.
Addendum fixes to ca370b49 (r52239) and a965ca6b (r52409).

- Fix the comments to explain what is really happening.

- Fix the boundary calculations in VidDisplayString() so that we can
  correctly display a character in the very last column before going
  to the next line, and fix similarly the vertical boundary calculation.

- Port the fixes to the ARM code.

+ Fix a potential bug in BitBlt() "4bpp blitting" in case Top == Bottom (i.e. Height == 0).
