This also uncovers very interesting design decisions like the copying of mutexes and condition vars depending on recursive locks that were previously hidden by shady c function calls.. We have perfectly good c++11 versions for all of that. While we're at it, also use the initialization list for the other (still copy constructable) vectors, which cleans up the radio interfaces.
