Allow monitoring the 'mirror' image write threshold and also report
correct aliases. Clean up some leftovers and improve docs while at it.

Peter Krempa (10):
  virDomainSetBlockThreshold: Document values of '@dev' better
  qemuDomainDiskBackingStoreGetName: Remove unused argument
  qemuDomainDiskBackingStoreGetName: Eliminate temp variable
  qemuProcessHandleBlockThreshold: Report correct indexes
  virDomainSetBlockThreshold: Clarify values of @dev the event is fired
    for
  qemuDomainDiskLookupByNodename: Remove unused 'idx'
  virStorageSourceFindByNodeName: Remove unused 'idx' argument
  qemuDomainDiskLookupByNodename: Look also for 'mirror' node names
  qemuDomainGetStorageSourceByDevstr: Look also in 'mirror' chain
  virDomainSetBlockThreshold: Mention that the event can be registered
    for <mirror>
