libvirt/python/libvirt-override.c
Taizo ITO 912f5e5884 Add virConnectGetVersion Python API 
adds a new python API call for retrieving the running
hypervisor version used by a connection: virConnectGetVersion

* python/generator.py: skip virConnectGetVersion from autogenerated
* python/libvirt-override-api.xml python/libvirt-override.c: define
  direct native bindings
