Robert Schmidt 7df8257526 F1AP: when UL_sync failure, send UEContextRelReq 
When a phone loses connection, it should not simply be removed but first
CU should be informed which will send a ContextRelCmd. Correspondingly,
when the RRC releases the UE, it does not send a UE Context Release Req

Cedric Roux 27395c083d hotfix: hardcode PLMN selection in the UE to value 1 (was 2) 
Fix the assertion:
Assertion ((instance_p->mnc_digit_length[ue_desc_p->selected_plmn_identity] == 3) || (instance_p->mnc_digit_length[ue_desc_p->selected_plmn_identity] == 2)) failed!
In s1ap_eNB_handle_nas_first_req() /home/ubuntu/tmp/openair3/S1AP/s1ap_eNB_nas_procedures.c:243

With this hotfix the UE selects the first PLMN sent by the eNodeB.

The UE has to select the correct PLMN from those received in SIB1. This
will be done with a later merge request.

Raphael Defosseux d254f5b522 Merge branch 'feature-s1-flex' into develop_integration_2018_w_41 
Introduction of S1-flex. It handles multiple PLMN IDs (up to 6) in the SIB as well as the selection of an MME based on the selected PLMN identity.

Major impact: changes on the eNB configuration files:

tracking_area_code = 1;

plmn_list = (
  { mcc = 208; mnc = 94; mnc_length = 2; },
  { mcc = 208; mnc = 95; mnc_length = 2; }
)

See https://gitlab.eurecom.fr/oai/openairinterface5g/wikis/s1-flex-conf-nnsf for more details.
