MR991: Remove hack in LTE PDCP for noS1 mode  
- Removes a hack which was used when LTE PDCP was used for NR in noS1 mode

MR993: UL and DL fixes LDPC short codewords 
- Fix UL & DL LDPC decoding for short LDPC code, e.g. Z_c is not multiple of 8
- Fix DLSCH data transmission with multiple DMRS symbols per slot
- small TA fixes on OAI 5G NR UE
- Implemented CQI measurement at NR UE
- NR UE cleanup 

MR1000: doc: fix build directory in BASIC_SIM.md

Setting the env variable RFSIMULATOR can be used instead of using the serveraddr parameter; it is to preserve compatibility with previous version.
## How to use the RF simulator options
Add the following options to the command line to enable the channel model and the IQ samples saving for future replay:
```bash
--rfsimulator.options chanmod,saviq
```
or just:
```bash
--rfsimulator.options chanmod
```
to enable the channel model.
set the model with:
```bash
--rfsimulator.modelname AWGN
```
Example run:
```bash
sudo RFSIMULATOR=server ./nr-softmodem -O ../../../targets/PROJECTS/GENERIC-LTE-EPC/CONF/gnb.band78.tm1.106PRB.usrpn300.conf --parallel-config PARALLEL_SINGLE_THREAD --rfsim --phy-test --rfsimulator.options chanmod --rfsimulator.modelname AWGN

With path loss = 0 set `-s 5` to see a little noise. `-s` is a shortcut to `channelmod.s`. It is expected to enhance the channel modelization flexibility by the addition of more parameters in the channelmod section.
Example to add a very small noise:
```bash
-s 30
```
to add a lot of noise:
```bash
-s 5
```
Example run commands:
```bash
sudo RFSIMULATOR=server ./nr-softmodem -O ../../../targets/PROJECTS/GENERIC-LTE-EPC/CONF/gnb.band78.tm1.106PRB.usrpn300.conf --parallel-config PARALLEL_SINGLE_THREAD --rfsim --phy-test --rfsimulator.options chanmod --rfsimulator.modelname AWGN
```
# Real time control and monitoring
Add the `--telnetsrv` option to the command line. Then in a new shell, connect to the telnet server, example:
```bash
telnet 127.0.0.1 9090
```
once connected it is possible to monitor the current status:
```bash
channelmod show current
```
see the available channel models:
```bash
channelmod show predef
```
or modify the channel model, for example setting a new model:
```bash
rfsimu setmodel AWGN
```
setting the pathloss, etc...:
```bash
channelmod modify <channelid> <param> <value>
channelmod modify 0 ploss 15
```
where:
```bash
<param name> can be one of "riceanf", "aoa", "randaoa", "ploss", "offset", "forgetf"
```
