* 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 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.
* Clang-formated UE, eNB and lib.
* Fixed compiling errors from clang-format.
* Fix linking issues introduced by clang-format
* Fix poor formating in initializing arrays of arrays.
* Fix mistake in conflict resolution on rm_turbo.c
* Re-apply clang format to gtpc_ies.h
