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 Paisana 44a9ad76f1 avoid sched_ue dangling pointer 
With the sched feature that allows scheduling in TTIs
ahead of time, there is no guarantee that when
the tti arrives to generate a sched result, the stored
raw sched_ue pointers are still valid. For this reason,
I now store the rnti and check if the rnti still exists.

Andre Puschmann a7911f0dab pdcp,rlc: refactor SDU queueing policy 
this patch refactors the SDU queuing and dropping policy of the RLC and PDCP layer.
the previous design had issues when packets have been generated at a higher
rate above the PDCP than they could be consumed below the RLC.

When the RLC SDU queues were full, we allowed two policies, one to block on the write
and the other to drop the SDU. Both options are not ideal because they either
lead to a blocking stack thread or to lost PDCP PDUs.

To avoid this, this patch makes the following changes:

* PDCP monitors RLC's SDU queue and drops packets on its north-bound SAP if queues are full
  * a new method sdu_queue_is_full() has been added to the RLC interface for PDCP
* remove blocking write from pdcp and rlc write_sdu() interface
  * all writes into queues need to be non-blocking
  * if Tx queues are overflowing, SDUs are dropped above PDCP, not RLC
* log warning if RLC still needs to drop SDUs
  * this case should be avoided with the monitoring mechanism

Andre Puschmann 06d31f46ba enb: set maximum allowed TTI difference between PHY and Stack TTI clocks for ZMQ 
this fixes the issue where PHY and MAC threads, and the processing
of events therein, are drifting apart too much.

This patch effectivly enforces a strong wait on the PHY if the
stack thread is too slow in processing its tasks.

For RF hardware the default is still 8192 TTIs, for ZMQ 1 TTI is used.

Andre Puschmann a0e4b18507 enb_mac: pre-allocate UE object for quicker PRACH/RAR handling 
we've seen long delays in handling PRACH on low-power devices
such as the RPi4. This was mainly caused by long delays
in creating the UE object on the fly during PRACH handling.

This patch pre-allocates one UE object that is then used
during the PRACH.
