osmo-trx: Add osmo_signal to stop whole transceiver chain correctly on error
Transceiver::stop() can only be called from either CTRL iface thread or from main thread (running osmocom loop). That's because stop attempts to cancel and then join all the other threads, which would then lock if attempting to stop from some of them. As a result, the best option is to indicate to the user of the transceiver option (osmo-trx.cpp) to stop it in a correct fashion by destroying the object from the main thread.
