Subject: [PATCH 13/20] block/qapi: Add indentation to bdrv_node_info_dump()
RH-Author: Hanna Czenczek <hreitz@redhat.com>
RH-MergeRequest: 145: Show protocol-level information in qemu-img info
RH-Bugzilla: 1860292

RH-Commit: [8/12] d3a697e81ab9828457198075e5815a592363c725 (hreitz/qemu-kvm-c-9-s)
In order to let qemu-img info present a block graph, add a parameter to
bdrv_node_info_dump() and bdrv_image_info_specific_dump() so that the
information of nodes below the root level can be given an indentation.
