fa75c57851
Add msgq to op25_decoder_ff to permit passing of snapshots to UI.
...
Change swabbing to use a bit decoding map, make argument types template parameters (so bvec/bit_vector can be interchanged).
Use a bit_queue (deque<bool>) for the frame buffer, pass this to all data_unit constructors.
Add plumbing to send snapshot to the UI.
New voice_data_unit as result of re-factoring LDU1/LDU2.
Re-factor op25_decoder_ff to use the bit_queue for correlation and frame header (and body - but that's ignored just now).
