[libvirt] PATCH: 1/28: Stubs for object locking APIs

[Daniel P. Berrange]

To facilitate later patches this introduces lock & unlock API calls for
each internal object which are just no-ops. Once all the drivers are
updated to call this at appropriate places, the stubs will be filled
out with actual locking impls. This ensures each intermediate patch
still results in a functional system
