Updated LTR Standard decoder state to new architecture to support
...
per-call recording and accurate state tracking.
Resolved issue with ThreadPoolManager limiting total number of scheduled
tasks (removed limiter - original intent is now OBE)
Updated ChannelState to better handle auxiliary decoder decode events,
so that when a fleetsync ident is at the end of the transmission, the
decode doesn't kick the channel back into a call state after it has
faded, causing static bursts and additional empty recordings.
Updated recording file name to include millisecond level precision, to
further avoid duplicate recording names

Decouples DecoderState from the Decoder and makes DecoderState inherit
...
from Module so that Decoder can function independent of DecoderSTate and
DecoderState can more cleanly interface with other modules.
Resolves issue with LTR-type decoders where the AudioModule was
filtering demodulated audio buffers before the decoder received the
audio - demodulated audio buffers are now copied before creating
AudioPackets.

Initial commit of redesigned internal processing and audio management.
...
Note: Several of the decoders are currently non-functioning in this
commit. If you want the latest functioning codebase, please checkout
the commit prior to this one. All decoders will eventually be updated
with this new architecture.
Currently broken:
- Logging and recording
- Aux decoders (Fleetsync/MDC/LoJack/Tait)
- LTR/Passport decoders
Changes in this commit:
- Module architecture for decoders and components with central
provisioning by the DecoderFactory
- Transition from Complex sample stream processing to float buffer
processing for improved memory management
- Redesigned filter structures - to support buffers and streams
- Resolved several memory leak issues
- Universal sharing of the thread pool manager
- Added centralized audio management with call/user prioritization and
new gui with mute/volume controls
- Embedded audio metadata for eventual streaming support
- Redesigned ProcessingChain to support independent re-use
- Added new TrafficChannelManager to handle traffic channel allocations
- Traffic Channel pool size and Call timeout available in P25 and
MPT1327 configs
- Redesigned channel and decoder gui components

P25 - updated automatic and direct frequency control to cleanup the code and allow P25 to better track frequency and PPM changes in the tuner and provide a cleaner implementation of the AFC component in the processing chain of all of the other decoders.
...
Changed C4FM symbol filter to reset frequency tracking values when the tuner's frequency or PPM values change.
Moved all frequency control pieces into the source.tuner.frequency package.

Added deinterleave, derandomize and the Golay(23,12,7) error detection and correction to LDU voice messages. Hamming edac still remains to be implemented. Plan to create a separate project to produce an imbe FormatConversionProvider that will convert 88-bit imbe frames to PCM audio that is then in a standard format for audio playback, recording, or conversion to another format like shoutcast.

P25 LSM work in progress. CQPSK demodulator is working now, but there is a slight phase error in the constellation (it's rotated right by 5-10 degrees). I'm not sure if this is an error coming from the decoder, or if it's reflecting a phase imbalance from the source tuner i/q data.
