It doesn't make much sense to pull whole libgtp to implement only the
user plan side of GTP. Let's drop it and add a minimal GTP-U
implementation here.

This is needed for instance:
* AUDIO: video calls
* GTP: secondary pdp contexts
For better abstraction, now both AUDIO and GTP conns use unique ID
namespaces, and one ID is used to identify each one. Each conn relate in
turn to a UE since a context_id is passed during connection
establishment.

This first implementation uses libgtp to manage the GTPv1-U socket and
pdp contexts, as a proof of concept to have something working for now.
At a later step, it is expected to drop libgtp and use some adhoc code
to handle GTP-U.
