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
