power_control: check-in new parameters and default values

For the sake of simplicity, the old structures that are still used
by MS/BS power control loops are kept in place.  Migration to the
new structures requires additional changes to the existing power
control logic, so it will be done in the follow-up changes.

The new parameters are integrated as follows:

  + struct gsm_bts - a BTS instance:
  |   Hard-coded default (fall-back) parameters for all transceivers.
  |
  +-+-> struct gsm_bts_trx - a TRX instance (transceiver):
    |     Default parameters for all logical channels inherited from
    |     'struct gsm_bts' at start-up.  May be overwritten by the
    |     BSC using ip.access specific 'Measurement Pre-processing
    |     Defaults' message on the A-bis/RSL interface.
    |
    +---> struct gsm_lchan - a logical channel (e.g. TCH or SDCCH):
            Connection specific parameters inherited from 'struct
            gsm_bts_trx'.  May be overwritten by parameters sent
            by the BSC in CHANnel ACTIVation and other messages.
