Summary: Loose files don't contain the original filename inside them, but rather the directory name is based on the sha1 hash of the filename. This means that given a remotefilelog data file, we can't find out the name of the file that it contains. Repack needs to know this (plus it's also useful for debug purposes), so add an additional file in the directory, `filename`, which contains the original filename of all the data files in the directory. It follows that `sha1(read(filename)) == basename(dirname(filename))` Reviewed By: DurhamG Differential Revision: D10516851 fbshipit-source-id: aeeb1a116e0d50a134c274c3bb31c7c26aa8015c

the server supports our custom getfiles method.
