* decouple EUTRA and NR stack classes
* implement dummy X2 interface with control and data plane methods
* implement eNB time source interface that PHY calls
this prepares for a change in which GTPU no longer writes into PDCP
directly but instead uses the stack as a wrapper.
For this the interface will be changed to use the EPS bearer ID instead
of the LCID
The stack will know which PDCP entity (EUTRA or NR) is currently associated
with the EPS bearer ID and will forward the PDU accordingly.
- use of inheritance to simplify testing
- removal of global network manager
- pass of custon socket manager to s1ap and gtpu ctors
- overhauled the registration of socket fd,callback in socket manager
* - 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.
