Re: [libvirt] [PATCH] test_driver: implement virDomainSetTime and update virDomainGetTime

Until now, testDomainGetTime would always return the same fixed
value
everytime it was called. By using domain-private data we can make this
API return the values previously set with testDomainSetTime, or use the
same old fixed value in case testDomainSetTime hasn't been called at all.

Looks like we're going to make more and more use of the private data, so at
some point it might be worth introducing helper structures to keep the master
structure (priv) tidy, but that's a patch for another day.
The code's alright, so once you split the changes it can go right in.
