* src/libvirt.c (virDomainBlockStats, virDomainInterfaceStats):
	  Added block device and network interface statistics.
	* src/xen_internal.c: Support for stats from Xen domains.
	* qemud/remote.c, qemud/remote_protocol.x, qemud/remote_internal.c:
	  Support for fetching device and network interface stats
	  across remote connections.
	* src/virsh.c: Added 'virsh domblkstat' and 'virsh domifstat'
	  commands to display stats.
	* docs/libvir.html, docs/hvsupport.html: Updated hvsupport
	  documentation.
