bundle2: a very first version of bundle2 unbundler

This changeset introduce an unbundler class to match the bundle2 bundler. It is
currently able to unbundle an empty bundle2 only and will gain more feature at
the same pace than the bundler.

It also comes with its special extension command in test.
