Two cec callbacks (adap_configured and received) could be called either with or without adap->lock held. This was 1) very confusing, and 2) could cause a deadlock. Stop 'overloading' these callbacks and just split them up according to the specific use-case. All adap_* callbacks now take the mutex, and all other callbacks do not.
