When we started out, Ericsson hadn't released yet their NS and BSSGP
modules. Let's port our logic over to their encoder/decoders, as they
are more complete (but less regular / more difficult to use).

It's unsure if the tests do anything useful. At least they build again
The fundamental problem is some clashes/overlap between our own
definitions for certain protocols and those that Ericsson released
later. Ideally we should use Ericsson whenever possible and resort on
our own ones only as a fall-back for those that don't exist, but
significant development has been done before Ericsson released their
codecs, so it's TBD for the future.
