Gerd Hoffmann c0fe07aa50 drm/qxl: rewrite framebuffer support
Completely different approach:  Instead of encoding each and every
framebuffer update as spice operation simply update the shadow
framebuffer and maintain a dirty rectangle.  Also schedule a worker
to push an update for the dirty rectangle as spice operation.  Usually
a bunch of dirty rectangle updates are collected before the worker
actually runs.

What changes:  Updates get batched now.  Instead of sending tons of
small updates a few large ones are sent.  When the same region is
updated multiple times within a short timeframe (scrolling multiple
lines for example) we send a single update only.  Spice server has an
easier job now:  The dependency tree for display operations which spice
server maintains for lazy rendering is alot smaller now.  Spice server's
image compression probably works better too with the larger image blits.

Net effect:  framebuffer console @ qxldrmfb is an order of magnitude
faster now.
