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.

CI: try to optimize the file system usage when building in the CI VM env. Increased the VM memory of one to allow linking
