* prevent segfault: guard access to RC.rrc with UETARGET
* in rlc_data_ind(): correct logic to test for all cases eNB, CU, DU, UE

  -- Moved the Gitlab notification within the try:
     As a result, when fails, the notification will be a fail

Although not used in the UE, we currently need to link the F1 library into it.
This is because we do not define ASN_DISABLE_OER_SUPPORT (otherwise, F1 has
compilation problems). In this case, some functions are apparently not
correctly defined, giving linker errors in the UE. Linking F1 in solves the
problem.

This is a hack. It would be better to be able to define ASN_DISABLE_OER_SUPPORT
and have no compilation errors or compile everything with
ASN_DISABLE_OER_SUPPORT except F1. I did not do this because I did not find
another way than add target_compile_definitions() to every target except F1
which adds many lines just so that one target (F1 ASN.1) compiles correctly (in
other words, F1 needs to be fixed).

Some #if defined(ENABLE_USE_MME)/#endif were added here and there.
The nos1 softmodem has not been tested, maybe this commit breaks
things.

Some deadcode was removed.

The implementation of the ID management is not finished.
It will only work if the handover is successful. No error
recovery has been done. For error recovery, we need to
implement the X2AP timers. As it is, in case of error, an ID
might very well never be released.

It has been tested with 1 and 2 UEs doing handover more or less
at the same time.

- manage target eNB based on target cell id received by measurement report
  for Handover Request
- manage source eNB based on association id for Handover Request Ack
- use only x2ap instance and not x2ap data instance points to x2ap instance

- free correctly in rrc_eNB_free_mem_UE_context
- check for existence of ue_context.handover_info in rrc_enb_process_itti_msg
- check return value sctp_peeloff in sctp_handle_new_association_req_multi
  and exit in case of failure
