Codebot 43082e8d6a enb/ue: turn various warning messages into info 
turn events that may happen in the normal life of a eNB/UE
into info rather than warning to allow strict
warning/error checking in tests.

Francisco 99f94d9a1a Bug fixes of srseNB scheduler TPC 
- fix encoding of TPC command
- use of exponential average with irregular sampling for the ULSNR average estimate.
  Turns out using a time-windowed average for the SNR was a bad idea.
  If the UL grants are very sporadic, the SNR time window will never have samples
  when a TPC is encoded
- update of TPC sched test
- other fixes in accumulators lib

Francisco 2dc3fce9bd fix derivation of UL-64QAM support from the UE Capabilities in the eNB 
Before this PR, the eNB was not activating UL-64QAM if the UE release was below 12,
due to an erroneous convertion of the ASN1 EUTRA Capabilities struct into the flattened
srslte::ue_capabilities_t.

With this PR, the eNB activates UL-64QAM for the following cases:
- UE category 5
- UE category 8 and release >= 10
- UE category UL 8 and release >= 12

Andre Puschmann 43a6cd50e5 rf_imp: fix stopping of AGC thread 
hard killing of AGC thread causes issue on some RF devices,
such as the N310. The thread still seemed to access the device while
the radio was already killed (or the streamer object deleted).

It's unclear why this isn't causing similar issues on B210 or X310,
at least not visible, but it is obviously not the correct way to stop a thread.

The patch now correctly sets the stop flag for the AGC thread, wakes it
it up and waits until it has terminated.

Andre Puschmann 286844b3dd mac_pdu: reset subheader state when deleting from PDU 
when packing MAC PDUs, adding a new SDU might fail, for example
because RLC couldn't provide a new PDU. The muxer then needs
to delete the subheader from the PDU again.

When adding a padding BSR at the end, the same subheader is again
used to store the BSR, so any state in that subheader should be removed.

In the particular case, this was causing an issue when logging a LBSR
because the LCG buffer states are printed using the payload buffer,
which was still pointing to some memory that was used when trying
to add the new RLC PDU in the beginning.

Andre Puschmann 035d989737 pdu: fix unpacking of LCG2 of LBSR MAC CE 
LBSR packing is fine but this makes the eNB do wrong things
because it thinkgs LCG2 has no or too much data to send.

LCG2 is our default LCG for DRB1. One occasion we saw the issue
is doing full rate TCP DL which requires quite a bit of ACK traffic
back to the sender. With the BSR for LCG2 being wrong, providing
UL grants was delayed and so the TCP DL throuhgput was very low.

In the log below we see that the buff_size[2]=1 so there is data to send.
Interestingly, the packing was correct so Wireshark displays it correctly.
But the unpacking not, as can be seen in the MAC log below which reports
0 buffer state for all LCGs

22:08:54.804792 [MAC ] [I] [ 5084] pdu_get: sdu_len=1212, channel.sched_len=1213, bsr.buff_size[2]=1

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

* 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

gracid f67a152a2a Remove unnecessary Lime calibration step from Soapy implementation 
When using srsLTE with Lime devices, calibration was performed before any configuration steps have happened, thus making calibration values invalid. Removing Lime specific calibration step from rf_soapy_imp makes so that devices will be automatically calibrated by SoapyLMS on rf_soapy_start_stream call.

    libsrslte_rf.so -> libsrslte_rf.so.0
