Francisco 102cb196e1 Addition of enb cfg option to choose between PUCCH with multiplexing and without. Change default prach offset to 4.

Francisco 34e39a9835 Implementation of scheduler algorithm to avoid PUCCH collisions 
- The cch_allocator considers the existence of a fixed PUCCH region dedicated to CQI, SR, and HARQ ACKs
- At the moment PUCCH multiplexing is not considered
- The PUCCH width was increased to accommodate possible PUCCH-ACK positions

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.

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
