Add support for data.tar, control.tar and control.tar.xz
Sync the deb(5) format support with latest dpkg, by allowing uncompressed tar members and xz compressed control.tar. This also refactors the control.tar member extraction by using ExtractTarMember(), which also means future changes only need to be implemented in a single place.
