[PATCH] fbcon: Console Rotation - Add support to rotate font bitmap

Browse source 
Add support to rotate the font bitmap.  To save on processing time, the entire
fontdata will be rotated on a console switch, then stored in a buffer private
to fbcon.  To further save on processing, the fontdata will only be rotated if
the font has changed or if the angle of rotation has changed.  Only a single
copy of the rotated fontdata will be kept.
