[libvirt] [PATCH 00/24] qemu: refactor node name detection



Since query-blockstats provides full hierarchy of node names without any doubtful
matching algorithm, use it to make the node name detector reliable.

Unfortunately some of the changes are ugly when viewed as a diff since they
delete and rewrite chunks of code.

This series can be fetched at:

 git fetch git://pipo.sk/pipo/libvirt.git node-name-detect-refactor-1
