WindowServer: Rename fb_data and friends to flush_rect etc

Browse source 
This was very badly named. All that the "FBData" struct contains is the
currently to-be-flushed rectangles plus a fullness flag, so it should
better be called FlushRectData. This rename is similarly applied to all
variable names.
