software/ors-amarisoft: enb: Start to generalize the code to handle multiple Radio Units
Add code to organize a registry of Radio Units and handle that registry generally everywhere.
RU registry is still populated from cell_list and in practice there still can
be radio units only of the same type, but besides slaplte.load_ru_and_cell
which is aware of that, the rest of the code tries to do everything as if
RUs of different type could be present simultaneously.
Now it is not only lopcomm who can do multiCELL, but also sunwave and SDR as well.
gNB also starts to gain support for cell_list, because cell_list loading is
uniformly applied to both eNB and gNB. However, since enb.cfg is not yet
prepared to handle multiple NR cells yet, there is an assert that in case of NR
there is only one RU/cell present there. We will remove this limitation in a
follow-up patch.
Later we will also change the loading to load RU descriptions from shared instances
and they won't be constrained to be Radio Units of the same type. But we need
to prepare a lot to be able to do that.
One more step forward towards MultiRU.
Tests will be added later as full tests for generic MultiRU.
Backward compatibility: no change for ORS and practically no breaking change for everything else.
