This commit introduces several enhancements in X2AP and RRC to deal with ENDC. The main goal is to deal with UE's on/off and with various errors. The following work is included: - DC prep and DC overall X2 timers - X2 messages for UE release and DC timers' timeout Open problems: - what to do when the UE sends an scg Failure? This commit removes the UE. And this removal may not be correctly done - UE removal in the gNB's PHY layer (a next commit is coming, but it is hackish and will need a rework)

An NR-capable UE will transmit some NR measurements. Once received, the whole process on nr-cell addition is started. It will fail quickly. Many things are still missing. What is not handled properly with this commit: - in x2ap_eNB_handle_sgNB_add_req we hardcode the gNB ID - nr triggering is done if we receive a measurement but this measurement is not analyzed at all - no timers (T_dc_overall, T_dc_prep) and as is the code fails and then the next triggering after UE reconnection will not work (x2 ID are not well handled here and there in the code) Note also that the gNB part has not been looked at all for this commit. This is work in progress...

This commit introduces X2AP timers (t_reloc_prep, tx2_reloc_overall). You need to set the values in the configuration file. X2AP can be enabled or disabled in the configuration file too (disabled by default). Some deadcode was removed.

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.
