A-bis/RSL: refactor handling of BS Power IE (power reduction)
According to 3GPP TS 08.58, section 9.3.4, BS Power IE indicates
the transmission power attenuation on a particular channel:
+--------------+---------+-----------------+
| Reserved (3) | FPC (1) | Power level (4) |
+--------------+---------+-----------------+
so let's change handling of this IE as follows:
- s/bs_power/bs_power_red/g, so it reflects 'reduction';
- store power attenuation value in dB, not in 2 db steps;
- get rid of ms_power_ctrl.bts_tx_pwr, it's always 0 anyway;
- fix rsl_tx_meas_res(): use lchan->bs_power_red;
- always check if FPC (Fast Power Control) flag is set;
- we don't support it, so reject messages containing it;
- fix rsl_rx_chan_activ(): properly apply the bitmask.
