Port enb specific classes to use srslog (#2155) 
* - Started porting the enb PHY layer to use srslog loggers.
- Updated srslog to manage the none level.

* Finished porting enb phy layer including the NR part.

* Ported MAC, GTPU, PDCP, RLC and S1AP enb classes to use srslog.

* Use new stack logger.

* Ported the enb RRC clases to use srslog.

* Remove unused log macros.

* Replace loggers in sched, sched_carrier, sched_helpers.

* Replaced loggers in sched grid.

* Replaced loggers in sched harq.

* Replaced loggers in sched ue.

* Replaced loggers in sched ue ctrl.

* Replace loggers in sched ue ctrl TPC.

* Replaced loggers in sched subclasses.

* Replaced loggers in rrc_meascfg_test

* Configure loggers in rrc_mobility_test.

* Fix compilation errors left out after the rebase.

* - Implement a custom log sink that will serve as a test spy to intercept and count the number of error and warning log entries.
- Adapt the erab_test_setup and rrc_mobility tests to use this new class and make them pass again.

* - Remove trailing new lines introduced in the rebase.
- Ported the sched_ue_cell class to srslog.

* Remove unused log member.

* Ported mac tests to srslog.

* - Removed remaining trailing newlines from log entries.

* Fix compiler errors detected in CI.

* Fix another static variable without definition passed to log lines.

* Fixed a bug in srslog::flush that would never end when the backend queue is full.

* Fetch the RRC logger instead of injecting it in the constructor.

Andre Puschmann 78b07daf3b pcap: make public interfaces thread-safe and handle fopen returning nullptr 
the previous patch only introduced a thread-safe queue between
PHY workers (writers) and PCAP writer thread (consumer).

However, it is also required to protect the ctor (and close()) to
prevent corrupted PCAP files.

The patch also correctly handles the case where the PCAP couldn't
be openend for writing and doesn't start the thread.

Pedro Alvarez 0c20b7a455 Added support for S1AP modify bearer request support. This includes: 
- Handle received E-RAB S1AP at s1ap.cc.
 - Added methods to rrc.cc, rrc_ue.cc and rrc_bearer_cfg.cc to handle erab modify request.
 - Made RLC add_bearer() function capable of re-creating the RLC entity.
 - Send RRC reconfiguration to the UE and reply to the EPC with S1AP
   modify bearer response.

This commit also adds support to srsEPC to send S1AP modify bearer request for
testing purposes.

hard killing of AGC thread causes issue on some RF devices,

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 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

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.

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

isn't transmitted for a RLC PDU that was segmented and
only the first segment had the P flag set.

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.

this patch refactors the MAC PDU class, the main changes are:

  This allows to have a single log entry per MAC PDU with all its
  contents.
  It removes the C-style fprint() method

* Simplity payload vs. w_payload_ce
  Before we've used payload when reading the PDU and w_payload_ce
  as a buffer when writing. In all getters we needed to differentiate
  between both. Now payload points to w_payload_ce initially and is
  only updated when parsing a new PDU.

* add various helpers, e.g. to get subheader index, update a BSR, ..

* fix PDU test to use new to_string() method
