[Qemu-block] [PATCH v3 08/44] block: Request child permissions in format drivers

[Kevin Wolf]

This makes use of the .bdrv_child_perm() implementation for formats that
we just added. All format drivers expose the permissions they actually
need nows, so that they can be set accordingly and updated when parents
are attached or detached.

The only format not included here is raw, which was already converted
with the other filter drivers.
