Andre Puschmann 83f24fbf77 rlc_am_test: fix max_retx test
the test should only check the correct signaling of the maxretx
to the upper layer.

Andre Puschmann ceacf8508d rlc_am_lte: fix handling of maxretx
this patch fixes the actions/handling after RLC detected
maxRetx reached for a given SN.

According to the TS, RLC should only inform upper layers and
not try to recover from the event itself.

As a consequence, we won't manipulate the Tx or Rx window.
As a result of this, we might retransmit a SN more than
the specified amount of times.

It's the task of RRC to reestablish the bearer to recover
from that.

Andre Puschmann fa23be4d6d rlc_stress_test: fix SDU generation
the PDCP SN was used to fill the SDU with data. But since
the max value isn't devisable by 256 it didn't always increment
correctly. Use a normal byte now that wraps correctly.

Andre Puschmann 62b2327178 rlc_am_lte: fix header reconstruction

Andre Puschmann 5e345df439 rlc_stress_test: make pedantic operation the default
among cleaning up the the stress test, it does:
* remove optional pedantic flag and make it the default to catch resegmentation issues
* use random SDU and MAC grant size the default
* use factory functions to create RLC configs (make maxretx configurable)
* remove reestablishment and print error when maxRetx is triggered
* fix NR PCAP usage and removes PCAP ifdef

this fixes an issue when the RLC bearer isn't reset from RRC.

Andre Puschmann 9c4146442a mac,phy: refactor NR MAC/PHY UL data passing interface
inspired by accepted (but not yet merged) PR to include the
(unique_)byte_buffer_t for MAC/PHY interfacing, this patch adds
a few more useful bits to that. Buffer management for UL data is now
done in MAC and only a pointer to the data is passed in the UL action.

* Move Tx softbuffer to MAC (until UL HARQ class is ready)
* Remove temparal data member in cc_worker
* Remove memcpy after packing MAC PDU
