        Post process the given dictionary of files (called from collectstatic).

        Processing is actually two separate operations:

        1. renaming files to include a hash of their content for cache-busting,
           and copying those files to the target storage.
        2. adjusting files which contain references to other files so they
           refer to the cache-busting filenames.

        If either of these are performed on a file, then that file is considered
        post-processed.
