Cedric Roux 4236ff2b3e nr: improve x2/rrc for ENDC 
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)

Cedric Roux 51ab31a3b9 trigger NR activation based on RRC measurements 
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...

Cedric Roux 9456fe584a x2ap: timers, cleanup 
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.

Cedric Roux c394188e73 x2: first implementation of ID management, some cleanup 
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.

Konstantinos Alexandris 02193f4bab x2: some cleanup in instance management 
- manage target eNB based on target cell id received by measurement report

- manage source eNB based on association id for Handover Request Ack
- use only x2ap instance and not x2ap data instance points to x2ap instance
