Can't declare it in gsm_04_08.h tough ... gsm_cbfn is defined in
gsm_data.h and trying to include that in gsm_04_08 just creates a
huge mess.

In the future we should avoid using a gsm_subscriber at all

now we can use the old model for paging and go through the
gsm_subscriber. This has the benefit of load balancing on
the BTS and such.

The gsm_04_08.c code is not forced to handle the IPA activation

this. The command is a bit misplaced, in one way it is no config

not belong into the VIEW_NODE either as it is manipulating content.
On this merge I have changed it to the ENABLE_NODE.
