Similar to what is already provided for power control loops. However,
there's no existing way to communicate TA control parameters from the
BSC to the BTS, so implement them locally in BTS vty.

gsm_bts_trx_alloc() already does initialize some fields of the
allocated 'struct gsm_bts_trx' instance, and having an additional
function for initializing the other fields makes no sense.
Note that I intentionally didn't merge a call to bts_model_trx_init()
into gsm_bts_trx_alloc(), because this would break some assumptions
regarding the order of initialization and cause regressions.
This also allows us to not call bts_model_trx_init() from tests.

First of all, there is no reason to use a void pointer because
it's always 'struct phy_instance'. Also, no need to encapsulate
this pointer into 'role_bts' because there are no other roles in
osmo-bts (we used to have shared headers years ago).
This commit also fixes a bug in test_sysmobts_auto_band(), where a
pointer to 'struct femtol1_hdl' was directly assigned to trx.pinst.

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.

All the Operative State logic to manage a RadioCarrier//BBTransc NM objects is
centralized in these FSM, where other parts of the code simply send
events to it.
This allows keeping state consistent and offloading logic from each bts
backend, since they are only required to submit events now.
The idea in the long run is to also replace other NM objects with
similar FSMs.
This improved logic fixes bug where PHY + RSL link became available before
OPSTART and hence op state changed to Enabled before receiving any OPSTART message.

This list is already a part of struct gsm_abis_mo.

Most likely, this part of the structure was copy-pasted from the
corresponding definition in osmo-bsc. In osmo-bts we always
establish a single per-BTS OML link, not per-TRX.

Operative state is mainly maintained based on 2 requirements:
* phy_link being in CONNECTED state
* RSL connection being up and ready
However, state change report triggered over OMl towards BSC was only
done upon the first event of the two. That means that if for whatever
reason the RSL connection was established AFTER the phy_link became
CONNECTED (ie receiving RSP POWERON in osmo-bts-trx), then the status
towards the BSC would not be updated and hence the BSC would still see
the Radio Carrier object as DISABLED.
The trx_set_available() function is renamed to trx_operability_update()
to keep the logic conditions in one place, and different events
triggering a change in state simply call the function and let it handle
the new state.

Move all struct gsm_bts_trx references from bulky gsm_data to its own
file containing all related definitions and implementations. Also move a
few functions clearly related to that object which were placed in bts.*
