osmo-bts/scheduler: provide actual C/I values to OsmoPCU
C/I (Carrier-to-Interference ratio) is a value in cB (centiBels),
computed from the training sequence of each received burst,
by comparing the "ideal" training sequence with the actual one.
So far, there was no way to expose more measurements from OsmoTRX,
excluding both RSSI and ToA. Since the new version of TRXD header,
we can receive C/I indications and send the averaged (per 4 bursts)
values to OsmoPCU (as a part of PCUIF_DATA.ind).
Please note that we also need to attach C/I measurements
to the following L1SAP primitives:
- PRIM_PH_RACH.ind,
- PRIM_PH_DATA.ind,
- PRIM_TCH.ind,
but this will be done in the follow up changes.
