[libvirt] PATCH 0/4: Openvz bridge support & related patches

This patch series is derived from Anton Protopopov /Evgeniy Sokolov bridge device patches. It first does some generic refactoring of MAC address handler in all drivers, then adds code to extract openvz version number, then does network config, and finally does filesystem config.
