Changes:
- Revised definition of "Serving Network".

for discovering PaC and CPAA to discover each other.
Basavaraj questioned about the need for PAA-initiated pre-auth, and I
agreed with his comment. But
PAA-initiated pre-auth still remains, based on Alper's comment "PANA
already supports PAA-initiated auth. So, unless we do anything special
(to eliminate this case), it comes for free."
Even though PANA supports PAA-initiated auth, I do not believe this is
applicable in the case where the target network to which the host is not
even attached would be able to trigger authentication.
So while the PAA-initiated auth makes sense in the regular PANA use case, I
don't see this as being valid in the scenario described in the pre-auth I-D.
The target network can trigger PAA-initiated preauth without requiring
MN to attach to the target network, with the help of the serving
network. For example, 802.21 network-to-network handover command allows
the serving network to indicate the target network about a possible
handover of the MN.

So I would recommend dropping this scenario from the I-D.
