A ChirpLiveEditorSet represents a conversation with a single radio
endpoint, but may involve multiple independent event streams. We
really don't need multiple threads and queues for talking to a single
radio, however radios with multiple sub-devices will end up with
different Radio classes by nature. So, instead of collapsing editors
into a single thread, we can just make them share a lock, established
at the EditorSet level, which is what this patch does.
This also means the other drivers (that I know of) that do their
own locking (kenwood_live, kenwood_d7, because settings) and ic9x
(because multiple sub-devices) can simplify and rely on this being
handled in the UI.
