Pedro Alvarez f9a2850d74 gnb,ngap: Added interface so the NGAP can pass a NAS message to the RRC
upon starting the RRC Security Mode command. This allows the gNB to
pass this message only after the SM procedure is complete.

Also made sure that the RRC notifies the NGAP upon the end of the
reconfiguration procedure, to make sure that the NGAP sends the UE
context setup response.

  - Fixed initalization of t-Reassembly
  - Fixed a bug in the packing of the status buffer.
Nacks now work for a single lost PDU.

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

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.

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.
