[libvirt] [PATCH 6/6] python: Add python bindings for virDomainStreamDisk[Info]

Wed Nov 17 19:14:03 UTC 2010
Enable virDomainStreamDiskInfo in the python API. dom.StreamDiskInfo() will
return a list containing a dictionary for each active stream. Each dictionary
contains items to report: the disk alias, the current stream offset, and the
total disk size.
virDomainStreamDisk() works with the automatic wrappers.
* python/generator.py: reenable bindings for this entry point
* python/libvirt-override-api.xml python/libvirt-override.c: the
generator can't handle this new function, add the new binding,
and the XML description
