RF simulator: Fix concurrency issues during new client connections
- Fix concurrency issues happening when a new client connects, sometimes
leading to a total softmodem deadlock.

Add WLS as a transport option for VNF/PNF, refactor existing options
This MR adds a new transport mechanism for the VNF and PNF split, using
the Intel WLS library, which makes use of DPDK and shared memory to
transport messages. This transport mechanism is what is used to
interface with Radisys ODU, while also working with OAI VNF/PNF.
The VNF and PNF have been refactored so that the transport-specific
functions are isolated from the rest of the logic, and as such,
interchangeable by means of function pointers.
The same change is done for the packing/unpacking procedures, allowing
to switch between FAPI and nFAPI encoding.
This MR also reduces the amount of duplicated code, by refactoring the
VNF with Aerial, which now only has the transport-relevant functions, as
well as the ones that are unique to it ( for example, the unpacking
procedures where a secondary data buffer is used for the message
payloads )
Additionally a new callback is added to the VNF to process
ERROR.indication messages, which currently only indicates which message
originated the error, and which error occurred.
Fix automatic SSS detection logic
When we try to detect a specific PCI and it fails, the SSS detection returns
successful detection with wrong frequency offset.
imscope updates
- Add CSV export button to imscope
- Add extra cache for IQ data in imscope record thread so that UE time domain
data can be kept until PDSCH is decoded.
- Add metadata to UE time domain samples scope
- Add UE pdsch pre-compensation IQ and PDSCH channel estimates
Make number of UL/DL actors in NR UE fully configurable
Due to different processing requirements on different CPUs it might be
beneficial to enable the users to set the number of UL/DL actors.
Allow disabling UL/DL actor frameworks and processing inline or setting
the number of DL/UL threads with --num-ul-actors/num-dl-actors
This was tested to work with 0 UL/DL actors with rfsim.
