move ASS-COMPL MGCP handling out of a_iface_bssap.c
BSSMAP Assignment Complete: sort MGCP handling upon Assignment Complete to the
proper locations. a_iface_bssap.c is not the right place to invoke the MGCP
related procedures.
- in a_iface_bssap.c only decode the IEs.
- call ran_conn_assign_compl() and pass decoded values.
- drop msc_assign_compl(), it was dead code; instead:
- add ran_conn_assign_compl()
- pass on all MGCP related info to msc_mgcp_ass_complete()
- move all MGCP ctx related handling from a_iface_bssap.c to msc_mgcp.c.
I'm dropping some comments to save some time, because if I adjust them IMHO
they would still anyway restate the obvious.
ran_conn_assign_compl() is now quite a thin shim, but it makes sense to have
it:
- This is the place that should tear down the ran_conn in case assignment
failed, left for a future patch.
- In the light of upcoming inter-MSC handover, ran_conn_assign_compl() will be
the place where the Assignment Complete message might be relayed to a remote
MSC.
