hyperv_driver.h comes directly from his original codebase. I just
changed indentation of the define to make cppi happy, so my copyright
notice is more debatable here than his. In contrast the other
secondary drivers were added by me to avoid libvirt trying to connect
to a non-existing libvirtd on the Hyper-V server (just the same reason
the ESX driver comes with stubs for all secondary drivers). Therefore,
I think there is nothing to be fixed on the copyright notice here.

Here's a v2 without the libvirt.spec.in part to match the v2 of 1/5.
