Same logic as previous commit, same caveats.

There was a problem with several UEs in the wireshark log. It seems that
wireshark needs the UE id otherwise it gets confused and sees retransmissions
where it's just another UE connecting and doing the same as a previous
UE.

Let's put kind of a UE id. Each RNTI seen by macpdu2wireshark gets an UE id
assigned the first time it's seen in a trace.

This is a bit hackish but seems to be fine.

We could have added UE_id in all the traces, that is change the T() calls
in the softmodem. It was less work to do it as it is, ie. only touch
macpdu2wireshark.c.

The RAR uses the same UE id all the time, may be a problem. To be refined
if needed.

You need a recent version of wireshark for this to work properly.
Successfully tested with 3.3.2.

If we NACK without SOstart/SOend then the other end of the RLC channel will consider all the bytes as NACKed and will have to resend them all. 
If another status is then reported before all the bytes are sent, and because we don't use SOstart/SOend this status will NACK all the bytes again, then all the bytes are to be sent again. 
And the cycle repeats. It will end with a max retx reached (which triggers RLF, Radio Link Failure).

MR1010 : NR UE: Fix for error message - no active DLSCH
- Fixes for the following error message at UE: [PHY] [UE][FATAL] nr_slot_rx 1: no active DLSCH

MR994 : Cleanup softmodem main
- Introduces --dlsch-parallel command line option to set the number of threads for dlsch decoding. If set to 0 (default) no parallelization. 
- Some cleanup in tracing and in nr-uesoftmodem.c data.

MR999 : NR FR2 RA
- Temporary Fix of RA procedure for FR2 (both gNB and UE)
- Fixes in gold sequence initialization at UE
- Moves 2nd downlink to slot 3 instead of 2 to avoid clash with UL DCI (only 1 candidate per slot in FR2 currently)
