[libvirt] [PATCH 1/5] add ploop fs driver type

[Dmitry Guryanov]

Ploop is a pseudo device which makes possible to access
to an image in a file via block device, like loop devices,
but with additional features: snapshots, write tracker
and without double-caching.

It used in PCS for containers and in OpenVZ. You can manage
ploop devices and images with ploop utility
(http://git.openvz.org/?p=ploop).
