Andre Puschmann 2be85217fd mac,ue: reset demux when restting MAC 
this potentially fixes the issue we see during HO and RLF
under high DL load.

The issue happens because buffered DL PDUs are delivered to
RLC after reestablishing RLC that confuse the receiving
RLC entity bc the sequence numbers are very high, as opposed
to begin with zero again after reestablishment.

Andre Puschmann f155b7a5d5 rlc: fix stopping of poll retx timer (#2006) 
* rlc_am: add TC for pollRetx timer handling

* rlc_am: fix stopping of pollRetx timer

stopping the pollRetx timer when receiving a status PDU
without checking the acknowledged PDUs is wrong.

if an ACK for another PDU, for which the polling bit has been set,
is still pending, it won't be rescheduled until another
PDU is transmitted that again starts the pollRetx timer.

this fixes the issue with missing RLC AM segment retx in #1992,
and #2003

Andre Puschmann 7cf919e2af Fix MAC PDU packing after sending Truncated BSR (#2004) 
* mac_test: add extended TBSR unit test

unit test to MAC UL packing after sending a TBSR

this fixes the MAC issues described in issue #2002

* mux: fix updating of LCG buffer state after packing PDU

we've previously lowered the buffer state of the LCG according
to the bytes that have been scheduled, but not according to
those that have been actually included in the PDU.

* proc_bsr: fix LCG buffer state updating for TBSR

when sending a TBSR do not update the internal buffer
state of the BSR proc.

This caused issues because the buffer state for all LCG that
are not included in the TBSR are set to zero, although at least
one LCG does have data to transmit.

* rlc_am: include LCID when logging retx of SN

Andre Puschmann 1b97ba5300 benchmark_radio: fix duration and thread priority 
I noticed that the app didn't configure the process with
RT thread prio. But it then turned out that in order to do
that we need to actually spawn a new thread. Also a few other things
didn't work out of the box.

In summary the changes are:
* fix duration to support more than 120s
* move main functionality in thread
* set high priority for radio thread
* only return success if no radio errors occured

Andre Puschmann 082e002b67 nas: fix airplane mode simulation 
the current implementation was somehow broken after a
NAS refactor. It was undetected because we didn't really
use it.

this fixes the simulation by using a single timer to simulate
airplane mode transitions.
the timer is rearmed in the timer_expire() function
if the correspondig event is set.

Has been tested to work well with, e.g.:

--sim.airplane_t_on_ms 5000 --sim.airplane_t_off_ms 10000

Andre Puschmann f647343f18 rlc_am: fix poll bit during header reconstruction 
this makes sure that the reconstructed RLC AM header
has the poll bit set when any of its segments had it set.

this triggered a bug in RLC AM because the Status PDU
isn't transmitted for a RLC PDU that was segmented and
only the first segment had the P flag set.
