bts_model: Allow TS connect to be processed asynchronously

This commit doesn't change internal logic of any model, only the API to
be able to return result of connect TS asyncrhonously since some models
(like osmo-bts-trx) require some time to process the result. This way
PDCH ACT/DEACT (N)ACK can be sent once the result of this long process
is known. For instance, nowadays in osmo-bts-trx we PDCH (DE)ACT ACK
before getting the result from SETSLOT on the TRX iface.

With this new API, bts_model_ts_connect doesn't return any value
synchronously. Instead, it is expected to always end up calling
cb_ts_connected with the return code from the TS activation process. 0
is considered a successs, while any other value is considered an error.
