Asynchronous NR PHY configuration (#3527) 
* Fix a race condition when accessing the NR PHY cfg by the RRC and phy workers.
Rework how the phy cfg is handled, now workers have their own copy that gets updated after a reconfig moving it out of the state class.

* Default initialize sf_len member in sf_worker for consistency.

* Asynchronous NR PHY configuration

* Fix compilation

* Corrected method override and fix unitialised value

* Added carrier equal comparison to avoid aligment byte padding comparison

Andre Puschmann dd5eda04e3 ue,rrc_nr: clear DRB to LCID lookup during RRC release 3 years ago
Pedro Alvarez fbcffb84bd Check if RLC is suspended before transmiting PDCP SDU. 
This was done to avoid integrity issues, when the UE's RRC erroneously sent
measurement reports while the re-establishment was already in progress.

As errously sending PDCP PDUs on DRBs can cause issues as well, this was
disabled too.

Carlo Galiotto ebaa71d190 ue,stdout: fix the SNR formatting in UE console (NR) 
When the SNR value is INF, the conversion to (int) causes
-2147483648 to be displayed in the UE console.
This commit fixes the formatting, so that the values INF or
NaN would be displayed as N/A

NOTE: The issue of getting an INF value for the reported SNR metric
still needs to be addressed separately.

Andre Puschmann d4a4da7ecc mux_nr: fix tiny issue in mux unit when adding SDUs of different logical channels 
this issue has a tiny affect when adding new SDUs from different logical channels
to an UL MAC PDU.

Since the MAC subPDU header is accounted for twice, less SDU payload may be packed.

The patch calculates the required header space and accounts for it in the scheduling.
Howerver, it is only substracted from the available space when an SDU was actually added.

Andre Puschmann cc2d71183e ue,phy,nr: fix race condition when setting UL grant for Msg3 
the Msg3 UL grant requires the TTI in which the RAR has been received
to calcualte the correct timing. There was a race between PHY and Stack
thread.

This patch circumvents the issue by removing a PHY state member that only holds
the RAR Rx timing. In the new interface the RA proc passes the Rx TTI
to the PHY again when setting the UL grant so the PHY can calculate the
correct timing without any state.
