This is split from series "[Qemu-devel] [PATCH v20 00/15] Drop in_use from
BlockDriverState and enable point-in-time snapshot exporting over NBD", with a
new patch 06 to avoid backing_blocker assertion violation.
v2: Address Stefan's comments on last two patches from v1, and add a patch 8 to
drop one more redundant bdrv_refresh_limits() after bdrv_set_backing_hd().
Thanks for reviewing!
