WindowSerer+LibGUI: Send multiple rects in invalidation/flush messages.

Browse source 
This patch moves to sending up to 32 rects at a time when coordinating the
painting between WindowServer and its clients. Rects are also merged into
a minimal DisjointRectSet on the server side before painting.

Interactive resize looks a lot better after this change, since we can
usually do all the repainting needed in one go.
