Aaron Lehmann 23e68679f0 Fix race condition when waiting for a concurrent layer pull ... Before, this only waited for the download to complete. There was no guarantee that the layer had been registered in the graph and was ready use. This is especially problematic with v2 pulls, which wait for all downloads before extracting layers. Change Broadcaster to allow an error value to be propagated from Close to the waiters. Make the wait stop when the extraction is finished, rather than just the download. This also fixes v2 layer downloads to prefix the pool key with "layer:" instead of "img:". "img:" is the wrong prefix, because this is what v1 uses for entire images. A v1 pull waiting for one of these operations to finish would only wait for that particular layer, not all its dependencies.
