[PATCH v3 02/11] qemu: Introduce qemuProcessHandleDumpCompleted

[John Ferlan <jferlan@xxxxxxxxxx>]

Add data to qemuDomainJobObj in order to store the dump completion
event information. Once the event has been received future code
waiting on the event will be able to process the stats and error
buffer. If there's no async job, we can just ignore.
