osmo-bts-trx: general handling of NOPE / IDLE indications
Each logical channel can now optionally have an additional handler,
that will be called when a NOPE / IDLE indication is received from
the transceiver. The aim of that handler is to keep the logical
channel state updated in case if one or more Uplink bursts are lost.
