1. Reverts GTPU_need_ITTI back to develop
2. Removed gdb helper and co files
3. Reverts changes to logging mechanism
4. Reverts changes to assert that were unnecessary
5. Reverts changes to VNF that occured from a bad merge
6. Removes unnecessary else() in gNB softmodem

Also, reverted some init_pdcp logic to match
the develop branch and added NSA mode. Lastly,
added additional error checking for cellConfig
to avoid crash in MAC layer.

This commit includes about 1/3 of the code clean up
in preparation for the merge to the OAI develop
branch. Several of the changes are white space changes,
removing of logs, comment removals, and updating any
changed code for our use-case to be clear for NSA mode.

comment out end_configmodule meanwhile someone verify all parameters that should have PARAMFLAG_NOFREE

The IP traffic still does not work. But we are
updating the NR UE scheduler to ensure we are are
sending true IP traffic. Also, we were getting an
assert(); as well, and there was no logs, so we
fix that in this commit as well.

Updated the configuration files. Added a sleep to
ensure that the LTE UE gets attached to the EPC
before the bearer is modified to be gNB. Updated
the ifconfig tunnel up command to be brought up
by the NR UE socket when in NSA mode. Lastly,
started the gNB PDCP layer in S1 mode.

more fixes on gcc warnings, misleading indentation and CPU mitigation when the traffic demand in 5G exeeds the available througput

Once the LTE UE's tunnel interface with the EPC
is ready to be established, if we are in NSA mode,
we do not want to launch the tunnel interface
from the LTE UE side, but in the NR UE. Via itti_msgs
we send the string containing the tunnel interface
'up' command to the NR UE and bring it up from the NR UE.

In the UE executable, delete the initialization of NR.nrrrc and check the NULL of NR.nrrrc
