IuCS, IuPS: move flag to use X.213 NSAP addr into ue_conn_ctx
The future perspective is to remember the preferred RAB Transport Layer Address encoding for each 3G cell that is connected, so store per UE conn instead of globally hardcoding. Add rab_assign_addr_enc member to ue_conn_ctx. Thus the iu_rab_act_cs() and iu_rab_act_ps() functions no longer need the explicit use_x213_nsap argument. Add include/openbsc/common.h in order to define the enum nsap_addr_enc, in a separate file to be able to easily include it in all of libmsc, libiu and gprs/* without creating include cycles. Set the rab_assign_addr_enc when an MM ctx is created for iu, and whenever the ue_conn_ctx for an Iu MM ctx is updated. This looks a bit clumsy so far, the hope is that there will be a nice way to setup the ue_conn_ctx prior to that. Change-Id: I49bb5736df7bdfdd55d3e7b74ee559595cfd2f7d
