Subject: Add support for writing by-hash dirs in apt-ftparchive

This option is enabled via the APT::FTPArchive::DoByHash switch.
It will also honor the option APT::FTPArchive::By-Hash-Keep that
controls how many previous generation of by-hash files should be
kept (defaults to 3).

Merged from https://github.com/mvo5/apt/tree/feature/apt-ftparchive-by-hash
