Re: [PATCH 2/3] qemu: Update to new design of 'block-export-add'

Since we've added the code prior to qemu setting the interface in stone
and thus it will be changed incompatibly and we already have tests for
the new interface we need to update the code and qemu capabilities data
at the same time.
Use a array of bitmaps as the 'bitmaps' argument instead of 'bitmap' and
bump qemu capabilities for the upcoming 5.2.0 release to commit TBD
The TBD proves that qemu is still in a state of flux; I'll be posting v6
of those patches today, but if they make it into soft freeze, we have
something to use. Whether that timing then works for you to get it into
this month's libvirt release, or whether you defer this patch to next
month, I think we'll be okay (the key part is that we avoid a libvirt
release targetting an unreleased unstable qemu interface, which patch
1/3 accomplished).

This part is fishy; but I presume it will be cleaned up when you resolve
the TBD in the commit message.

Still waiting on qemu, but once that is in, the code changes plus your
respin to fix the commit message and testsuite are good enough to add:
