Re: [libvirt] [PATCH 00/18] split virDomainDiskDef

I still have quite a bit of work to consolidate util/virStorageFile, conf/snapshot_conf.c, and the new struct in this series to all share the same common struct (basically, moving the struct created in this series over to util). But by refactoring the most common accesses to go through functions instead of direct field access, I've limited the amount of code that is actually impacted by using the new struct. In general, this series should not be changing any behavior.
