Robert Falkenberg 7e7eceda15 ctest: Viterbi test skips 0dB for non AVX2 machines 
The accuracy of the 8-bit implementation of the Viterbi decoder used on
non-AVX2 machines falls below the theoretical accuracy at 0dB.

Robert Falkenberg 06f2ab6d7c ctest: PDCCH test skips 100PRB for non AVX2 machines 
The current 8-bit Viterbi decoder implementation for SSE (non-AVX2)
is not accurate enough to reliably decode all messages with a
code rate ~0.9 or higher, e.g. DCI format 2/2A messages in 100 PRB cell
at aggregation level 0.

Pedro Alvarez 7ac7c8673a lib,rlc: Fixed issue where `p` bit was not checked if PDU was outside of 
the RX window. This could lead to a data stall, where TX keeps retx'ing
the same PDU to request a status report.

Robert Falkenberg a11291eb08 lib,rlc_am_nr: fix handling of NACK ranges with SO reaching SDU edge 
This changes the handling of NACK ranges with segment offset (SO),
where either so_start or so_end reach the edge of a full SDU.
That SDU is then NACK'ed as a whole, rather than as a segment
from 0 to 0xFFFF.
Otherwise, the search for segments will fail if said SDU was
initially sent as a whole (without segmentation).

Robert Falkenberg fccfd5e140 lib,rlc_am_{lte,nr}: fix/add tx_window overrun protection 
This commit fixes as bug causing a crash of the eNB in case
of many pending RETX and the reception of a trimmed PDU.
The following sequence leads to a crash:
- RETX queue contains many PDUs for RETX
- Receive trimmed PDU containing a trimmed subset of NACKs
- RETX queue is cleared and re-populated with a trimmed subset
- After all RETX (/!\ trimmed subset) is done, continue TX new PDUs
- tx_window blows up
- tx_window overflows if another status PDU is not received in time
- Overflow overwrites oldest element in tx_window
- Handling of next status PDU fails due to missing elements in tx_window
