Modify not to assert a part in L2 FAPI simulator because it's possible to differ timing(frame, subframe) between eNB and UE.

Change not to watch timing in MSG2 and MSG4 procedure in L2 FAPI simulator because it's possible to differ timing(frame, subframe) between eNB and UE.

Fix for problems that L2sim finishes in case of multiple UEs and UE L2sim keeps wating for a signal.

Fix for problems that eNB keeps waiting for signal of unused thread and eNB_thread_rxtx isn't created.

Change type for 256UEs test , abnormal exit and add definition of UE's thread ID for multiple UEs simulation.

    also adding TDD IF4p5 testing
    removing basic-sim TDD 5MHz DL iperf test

This reverts commit d7441543.

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.
