[RFC] Framebuffer rotation patch

Sending a preliminary framebuffer rotation patch.

You can use videotest to see 4 tiles rotated from the same bitmap data.

Known issues:

- font glyphs and terminal do not rotate properly
- no accelerated blitters for rotated modes, at least the 1bit blitter
should work

To be done

- split out signed rectangle patch that changes graphics coordinates
from unsigned to signed
- make up some naming scheme and rename functions and macros accordingly
- make up some acceptable way to specify framebnuffer rotation in the
environment like gfxmode
