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

qemu decided to modify the arguments of 'block-export-add' to include an array of bitmaps rather than a single bitmap. 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 ---
