Introduce a new QAPI type BlockGraphInfo and an associated bdrv_query_block_graph_info() function that recursively gathers BlockNodeInfo objects through a block graph. A follow-up patch is going to make "qemu-img info" use this to print information about all nodes that are (usually implicitly) opened for a given image file.
