This series adds for point-in-time snapshot NBD exporting based on
drive-backup. The ideas is described below and patches followed (the missing
part is item 3, which work is in progress by Ian Main who will have another
patch on it). As the work does not overlap, these series should be quite
Device attach, NBD server and block job can share a BlockDriverState,
this patch makes them to use refcount to grab/release a bs so they don't
interfere each other with BDS lifecycle.
Local BDS allocation/releasing don't need to use refcount to manage it,
just use bdrv_new() and bdrv_delete().
Previously, nbd call drive_get_ref on the drive of bs. A BDS doesn't
always have associated dinfo, it's more proper to use bdrv_get_ref().

The patch only does a rename: bdrv_in_use is obsecure literally (any BDS
is certain to be used somewhere). Rename it to bdrv_is_shared since we
have reference count now and the user number of the BDS is reflected
there.
