this series adds logical block provisioning functions to the iscsi layer.
it adds the ability to write sparse images to iscsi targets which
support UNMAP and LBPRZ via qemu-img. additional block-migration is
enhanced to support an encoding for zero blocks on the network
and efficiently writing those zero blocks at the destination if
the driver supports it.
many thanks to Paolo, Kevin and Ronnie for their useful comments.
