Proper refactoring of the framebuffer drawing routines. This time it's
not only the merging of duplicated code. It isn't half finished either
so the various combinations of foreign endianness, pixel reversing, bits
per pixel, cpu word sizes and byte order should work.

Added myself to look after this code. Based on the time spent on proving
it I don't expect a busy inbox. Famous last words.

I'd like to give this patch a chance to live in for-next for a few days, although
I don't like such a big rewrite as one patch. But in this case it's probably necessary
to make an exception.

Important: please add a proper commit message to your patch!
Explain why you do that, and what advantages it gives.
Describe what should be different. Is something maybe faster or slower?

Then, the patch did not applied for me and git mentioned that the patch
was corrupt. Not sure yet, if the problem is on my side...

I've applied that series to the fbdev git tree so that it gets some testing...
