[libvirt] [PATCH v3 00/31] Implement sparse streams for libvirt



v3 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_streams2

diff to v2:
 - renamed APIs from Skip & GetHoleSize to SendHole & RecvHole
 - switched from 'unsigned long long len' to 'long long len' (where len is size of a hole)
 - introduced @flags to public APIs for future extensibility
 - couple of coding style fixes
 - couple of fixes suggested by John in review of v2

As expressed earlier, a lot of these patches should have Reviewed-by tag as
John reviewed majority of them. But we don't have a clear agreement when to use
the tag, so I'm not putting it in just yet. However, will do before pushing.

Some patches were ACKed. However, changes described above changed them, so I'm
not sure ACK still stands.
