openpgp: Rename every from_buffered_reader to from_cookie_reader.

  - This is an internal interface that uses our reader stack's
    cookie.  We need this to traverse the buffered reader stack.  We
    did not, however, expose it as an external interface, because we
    didn't want to bake in the cookie type into the API.

  - Having a public API that operates on buffered readers is
    convenient: the current Parser::from_reader operates on
    io::Readers, and will most likely construct a
    buffered_reader::Generic from it.  This will eagerly buffer some
    data, making this interface unsuitable if you want to read in one
    artifact (e.g. an MPI) without consuming more data.

  - Renaming the internal functions gives us a chance to add a more
    general buffered reader interface.
