[libvirt] [PATCH 0/2] Disallow the usage of the same target dev value

https://bugzilla.redhat.com/show_bug.cgi?id=1142631 Patch 1 was found when adjusting the bz to get the disk by the pool source instead of directly by file attribute. When using domblklist, the source wasn't displayed. Followed the model of the iscsi '@name' and added '@volume' (eg, <source pool='default' volume='test-1g.img'/>) Patch 2 started as a simple (hah!) double loop looking for duplicate dst strings. I chose a separate API called before qemuCheckDiskConfig since it's more of a "common" check that could be used by other drivers as opposed to the perhaps more specific single disk checks made. Besides I didn't want a ndisk factorial checking algorithm each time a disk was checked for something that could be checked once. With the code in place, running make check tripped over a number of existing tests that duplicated that '<target dev=...' value, so I fixed those. Of interest for a few was that the test would duplicate the supposedly unique alias id - those are cleaned up as well as a byproduct of the changes.
