bundle-uri: download bundles from an advertised list

The logic in fetch_bundle_uri() is useful for the --bundle-uri option of 'git clone', but is not helpful when the clone operation discovers a list of URIs from the bundle-uri protocol v2 command. To actually download and unbundle the advertised bundles, we need a different mechanism. Create the new fetch_bundle_list() method which is very similar to fetch_bundle_uri() except that it relies on download_bundle_list() instead of fetch_bundle_uri_internal(). The download_bundle_list() method will recursively call fetch_bundle_uri_internal() if any of the advertised URIs serve a bundle list instead of a bundle. This will also follow the bundle.list.mode setting from the input list: "any" will download only one such URI while "all" will download data from all of the URIs. In an identical way to fetch_bundle_uri(), the bundles are unbundled after all of the bundle lists have been expanded and all necessary URIs.
