stevie 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).

stevie 725a8442bb BUG: fails to correlate on 32 bit platforms. CAUSE: ulong initializer to bitset 64bits on amd64 but 32bits on 686 and is being truncated. FIX: abandon bitset and use a uint64_t instead.

stevie 7650800ade Have data_unit::make_data_unit accept the frame body in a const_bit_vector. 
Move BCH decoding back into op25_decoder_ff, it belongs there.
Refactor so different classes do the expected jobs (even though no class actually does anything yet).

 2008-10-29 11:41:41 +00:00
stevie ead89bda24 Abandon idea of P25 decoder being a sink. This means subclassing gr_block instead of gr_sync_block, some name changes and allowing for audio output from the block.
