[libvirt] [PATCH 0/5] Misc changes to domain driver stuff

The patches that follow make some changes to the domain driver infrastructure, and the QEMU driver. The important goal is to improve the concurrency of the QEMU driver, by allowing multiple readers on the driver (change mutex to a rwlock) and removing the O(n) locks on the virDomainObjPtr instances These have not been heavily tested yet, beyond checking the TCK passes with QEMU driver. I just send them now for early review, while I continue to work on the rest of the QEMU monitor related patches which this series supports. The CIL object locking test also needs to be extended to understand the idea of RWlocks instead of just mutexes so it can properly validate this code Daniel
