Andre Puschmann 0a16f48869 gw: fix race condition
GW thread was checking the default_eps_bearer variable without
protection. RRC could update it when deleting DRB or receiving RRC
connection release.

Andre Puschmann 483a216bd5 ue,stack: refactor handling of radio bearears in UE stack
this is a rather large commit that is hard to split because
it touches quite a few components.

It's a preparation patch for adding NR split bearers in the next
step.

We realized that managing RLC and PDCP bearers for both NR and LTE
in the same entity doesn't work. This is because we use the LCID
as a key for all accesses. With NR dual connectivity however we
can have the same LCID active at the same time for both LTE and NR
carriers.

The patch solves that by creating a dedicated NR instance for RLC/PDCP
in the stack. But then the question arises for UL traffic on, e.g. LCID 4
what PDCP instance the GW should use for pushing SDUs. It doesnt' know
that. And in fact it doesn't need to. It just needs to know EPS
bearer IDs. So the next change was to remove the knowledge of what
LCIDs are from the GW. Make is agnostic and only work on EPS bearer IDs.

The handling and mapping between EPS bearer IDs and LCIDs for LTE
or NR (mainly PDCP for pushing data) is done in the Stack because
it has access to both.

The NAS also has a EPS bearer map but only knows about default and
dedicated bearers. It doesn't know on which logical channels they
are transmitted.

Upgrade loggers in srsue (#2163)
* Replaced UE logger in the ue class.

* Replaced loggers in the main phy class and prach.

* Replaced loggers in phy common and ta_control.

* Replace loggers in cc and sf workers.

* Replaced loggers in intra_measure, scell_recv, search, sfn_sync, sync.

* Remove last uses of the old loggers in the main phy class.

* Remove stray newline in logs.

* Replaced loggers in ue gw.

* - Started to replace loggers in the ue stack.
- Replaced loggers in usim and pcsc.
- Adapted nas and usim tests.

* Replace loggers in nas.

* Added missing log init calls in two previously modified tests.

* Replaced logger in nas idle procs.

* Replaced loggers in nas emm state.

* Replaced loggers in tft packet filter and adapted tft test.

* Replaced loggers in main RRC class.

* Replaced loggers in RRC cell.

* Replaced loggers in RRC meas.

* Replaced loggers in rrc procedures.

* Started logger replacement in MAC layer, more precisely in demux and dl_harq classes.
Been unable to inject loggers in construction for dl_tb_process due to very weird static assertions in the std::vector code being the type not constructible which is not true, so instead use the main MAC logger directly.

* Replaced loggers in mac mux class.

* Replaced loggers in mac pro_bsr.

* Replaced loggers in mac proc phr.

* Replaced loggers in mac proc SR and RA.

* Replace loggers in mac UL HARQ.

* Replaced loggers in main ue stack class.

* Fixed nas test crashing due to a null string.

* Ported mac_test to use the new loggers.

* Removed TTI reporting for the PHY log as the old logger did.

* Replaced loggers in UE phy tests.

* Configure loggers in nas_test.

* Replaced loggers in rrc_meas_test.

* Replaced loggers in rrc_reconfig_test.

* Added missing newline in tft_test.

* Fix compilation errors in TTCN3 tests.

* Fix linker error detected in CI and warning.

* Replaced loggers in TTCN3 tests.

* Fix a text replace error in some log messages.

* Remove trailing newlines from log entries.

* Remove old logger from rrc.

* Flush backend before printing the test status.

* - Fix compilation error from previous rebase.
- Remove trailing newlines from some missing log entries.

Andre Puschmann 3f613d7183 nas/gw/rrc: make LCID for DRB dynamic
- add interface to RRC to allow NAS to query the DRB for a given
  EPS bearer id
- extend interface for NAS to setup GW to also pass LCID of bearer
- in NAS, use this new interface to pass actual LCID of the default
  DRB when creating the TUN device

Andre Puschmann 65f50cd7ba introduce new UE layer design
- abstract UE object now consists of a radio, a PHY, and a stack layer
- add new stack abstraction layer that combines MAC, RLC, RRC, PDCP, NAS and GW
- PHY layer now has a single stack interface and does not talk to MAC and RRC seperatly
