[libvirt] [PATCH v2 00/38] Implement sparse streams for libvirt

v2 of: https://www.redhat.com/archives/libvir-list/2017-April/msg00671.html All the patches can be found on my github: https://github.com/zippy2/libvirt/tree/sparse_iohelper5 diff to v1: - Do not drop the pipe in 06/38. Use it for signaling to the event loop that there's a message in the queue waiting to be processed. - Dropped the error report in virNetClientStreamRecvPacket in 31/38. It was useless.
