Re: [libvirt] [PATCH 5/7] qemu: block: Use simple backing stores string format if possible

In case when the backing store can be represented with something simpler such as an URI we can use it rather than falling back to the

json: pseudo-protocol. In cases when it's not worth it (e.g. with the old ugly NBD or RBD strings let's switch to json).

The function is exported as we'll need it when overwriting the ugly strings qemu would come up with during blockjobs.
