Adds a dependency on filepath-bytestring, an as yet unreleased fork of filepath that operates on RawFilePath. Git.Repo also changed to use RawFilePath for the path to the repo. This does eliminate some RawFilePath -> FilePath -> RawFilePath conversions. And filepath-bytestring's </> is probably faster. But I don't expect a major performance improvement from this. This is mostly groundwork for making Annex.Location use RawFilePath, which will allow for a conversion-free pipleline.
