Also, finally committing the critical logs for IP traffic.

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.

Also changed logic in the NR UE schedule to read
IP traffic. Also, configured the RLC layer in the
NR UE softmodem and the DRBs with the cRNTI once
the RACH procedure is complete in the NR UE.

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.

Unnecessary dl_ind_type array for logging.

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.

Also, updated the filing of the DCI payload
based on the actual number of recevied bits
and not based on the max number of rx'd bits.

This commit includes several changes.
First, it updates the way we fill the uplink
UCI indication. This still has some todo comments
since all the fields in this ind were hardcoded.
It also updates the pack and unpack functions for
the NR_UCI incations. Lastly, it includes updates
to the gNB UCI scheduler. The updates in the gNB
were cherry picked from develop. There are two updates
to the VNF which allow the VNF timing/slots to be
adjusted based on the received timing_info packets
from the VNF. This adjustment was disabled in IISc's
nFAPI code. For now, it is improving the timing
between the VNF and PNF.

Currently, the pull8 in nFAPI of the VNF
is failing.

The previous two commits did not correctly check
the gNB sfn and slot. The code now correctly sets
the slot in which the PUSCH is SCHEDULED, not the slot
the rx is expected. Also, the sfn/slot is only updated
if we do in fact schedule a PUSCH.

Also, we are now updating ul_tti_future
for every index in the array, not just slot 7, 8, and 9.

Although the timing isnt perfect, if the VNF adjusts
in the middle of scheduling a DCI the gNB would try to
send two DCIs for a certain sfn/slot; this commit will
stop that from happening. The timing issue still persits.

Also, added functionality to fill tx_req in NR UE
when a DCI is received after the slot indication.

Most notably, nfapi_rx_indication_pdu_t.data type is changed from
`uint8_t*` to `uint8_t[]`.  Also, renamed from `data` to
`rx_ind_data` to make it easier to find.

These are all superficial, low-risk changes

It also includes the queuing development. The idea
is that the 5G Userplane messages will be filled
and configured the same as previous commit, but
the uplink messages will be queued and then sent to
the gNB during the correct slot. Still WIP.

Also ported in new gNB ulsch scheduler code from
Eurecom/develop branch.

Enable -Werror compiler option

See merge request aburger/openairinterface5g!43

Fix some warnings, too.

Starting to complete the final fill of
dl_indication and an rx_indication

This commit properly is filing the dci_format but the
rx_ind and dl_ind has not been updated in the NR UE
prior to sending to gNB. The chnages in this commit
to properly fill the dci_format include:
- filling the dci canidates every slot indiction
- checking for a dl_tti/ul_tti containing a dci
- when dci payload is received we use the filled
  dci canidates to update the dci_format

Also, a bug in LTE UE is found where we are indexing
passed the end of ue_sdu array. We added a check for this.
Furthermore, in the nr_ue_scheduler we were utilizing
tx_req but the memory wasnt properly initialized.

Adjusted UDP port ids for multiple UE connection with proxy

See merge request aburger/openairinterface5g!41

Also started handling ul_dci that is received in NR UE.
We now receive dci format 01, 10, and 11 at the NR UE.
The dl_info being filled in NRUE was not memset to 0, that
has been added. Additionally, we will need to get the dci_format
based on the length in the dl_config structs and map it.
For the moment the dci_format values are hard coded.

Also, there is not a field for dci_format in
nFAPI so there is a way it is detected by the NR UE.
For now, we have hardcoded the value in the stub when
we receive the DCI. Lastly, updated the nr_harq_handling
in the gNB.

This commit includes the changes made to gNB.
All of these changes were cherry picked from
the Eurecom/develop branch to ensure the
CFRA procedure is working. Without these changes
there were several seg. faults.

This commit contains the changes to the OAI code in
the NR UE and in nFAPI.
- Filling crc_ind for msg3
- Updating pack/unpack of CRC_ind
- Creating phy abstraction CRC_ind handling in VNF
- Removal of old comments
- Only sending on RACH in phy_stub
