Now, we are able to fill the UE_Capability_Info that
the LTE UE and eNB are expecting. We then are able to
generate a RRC_DCCH_DATA_COPY_IND to trigger the
processing of the UE_Capability_Info (and sending the
info to the eNB). The info being received at eNB has not
been tested yet.
Also some code clean up.

The encode is still  working but now we need to
add in some new functionality to handle NR Capabilites.

Also updated the generate_nrMeasReport().
The uper_encode_to_buffer is still not working.

Also removed the [eNB_index + 1] saving/writing
in the process_MeasObj function. This indexing
was incorrect. Also cleaned up the code, fixed
ssRSRB -> ssbRSRP. Lastly, added assertFatals
around indexing in process_measObj function.

Added check and logs. If we change ind = 1 it
crashes the LTE UE so we log for now. Also cleaned
up a lot of the code. Lastly, we set freed vars to NULL.

This commit has several other changes. The changes
include the following:
1. Changed the port numbers for the NRUE<->Proxy
2. Fixed the send to function in the NR UE
   (Previously only sending buffer not buffer+msg_type)
3. Updated pack/unpack of the SSB PDU (new RSRB field added)
4. Fixed several NR logs
5. Opening socket with NRUE<->Proxy AFTER receving RRC
   measurement request from the LTE UE

This commit also removed MAX_NUM_NEIGH_CELLs and
replaced it with MAX_GNB_CELLS. This was a minor change
OAI added. The standalone sockets for the NR UE correctly
connect to the proxy. We are currently receiving dl_tti
messages from the proxy.

Also enabled X2 when we are not using the EPC
Added in the case statement for handling the
dl_dcch_msg from the NR UE. Also added in the
proper decoding of that dl_dcch_msg and freeing

This commit removed all the linking errors
between the NR UE and the LTE UE. This was done by
changing:
-      rrc_data_req_ue
+      rrc_data_req_nr_ue

This commit is not currently building, but I wanted
to be able to save the changes that I have added.

NR UE is ending early. LTE is not passing at all.
X2 interface is not working either.

1. restoring ci test environment.
2. packet drop disabled.

assert() statements were enabled for C code but disabled for C++
code.  With this commit, assert() is enabled for both C and C++
for RelWithDebInfo builds.

With a small number of runs with 16 UEs, I've seen this
AssertFatal fail twice.

There are many other places in the code that simply skip over
ulsch[i] values that are NULL.
