The first part of list_file_blocks transforms the pool configuration output by zdb -C $pool into shell code to set up a shell variable, VDEV_MAP, that maps from vdev id to the underlying vdev path. This variable is a simple indexed array. However, the vdev id in a DVA is only the id of the top level vdev. When the pool is mirrored, the top level vdev is a mirror and its children are the mirrored devices. So, what we need is to map from the top level vdev id to a list of the underlying vdev paths. ist_file_blocks does not need to work for raidz vdevs, so we can disregard that case.
