The RNG grammar did not allow arbitrary interleaving, which makes
it harder than necessary to create a new volume from handwritten XML.
(Compare also to commit caf516db for pools).
* docs/schemas/storagevol.rng: Support interleaving.
* tests/storagevolxml2xmlin/vol-file-backing.xml: Test it.

v2: correct version (actually applies to libvirt.git, rather
than depending on unpublished intermediate commits)
reviewer's note: see bottom for easier-to-review schema change
