Feature-for-feature, config-for-config port of the Python ipsc2hbp IPSC↔HBP
translator to dependency-free C11 (links only libc).
- src/dmr/: self-contained DMR DSP/FEC library (BPTC(196,96), embedded LC,
AMBE 49<->72, RS(12,9), Hamming, Golay), validated bit-for-bit against
dmr_utils3 via golden vectors.
- src/: config (in-tree TOML parser), logging, poll() event loop, UDP,
SHA-1/SHA-256/HMAC, IPSC master/peer protocol, HBP client, call translator.
- Single-threaded event loop mirrors the original asyncio design.
- tests/: DSP self-test + byte-for-byte translator parity vs the Python
reference (IPSC->HBP DMRD and HBP->IPSC GROUP_VOICE).
make && make test both pass; integration-tested against the fake peer/master.
