[libvirt] [PATCH v3 4/6] qemuDomainObjPrivate: Introduce blockJob condition

So far the condition is not used, but will be. There are some operations, where we actively wait for a block job to complete. Instead of locking and unlocking the domain object, entering and leaving monitor, lets just use a condition and let our monitor event handling code wake up when needed.
