Merge remote-tracking branch 'remotes/stefanha/tags/block-pull-request' into staging

Pull request

This pull request contains a virtio-blk/scsi performance optimization, event
loop scalability improvements, and a qtest-based device fuzzing framework.  I
am including the fuzzing patches because I have reviewed them and Thomas Huth
is currently away on leave.
