[Spice-devel] [PATCH] async and s3 support

[Alon Levy]

This is a redoing of async io support using spice api changes, and on top of
it the s3 support patches using the original suggestion of an added api call (but
named flush_surfaces instead of update_mem).

Recap: After the previous discussions with Gerd and Yonit we agreed a way to
call flush_all_qxl_commands is needed before suspend, and so a change of the
spice server api is inevitable. As a result a simpler implementation of async io
is possible using yet more spice server api changes (async io means here io
calls were the completion is notified by a new interrupt and so the vmexit is
much shorter)

Alon Levy (2):
  server: add async io support
  server: add QXLWorker.flush_surfaces_async for S3/S4 support
