Move the two-table fast match finder into Rust while retaining a small C
projection of the private match-state. The Rust implementation handles normal,
attached-dictionary, and external-dictionary matching without exposing the
full C context ABI. The C entry points and build-time exclusion guards remain
unchanged for configured consumers.
Document the migrated matcher in the Rust component map and narrow the
remaining-C boundary accordingly.
Test Plan:
- cargo test --all-targets
- cargo test --target i686-unknown-linux-gnu --all-targets
- cargo clippy && cargo clippy --benches && cargo clippy --tests
- cargo +nightly fmt
- make -B -C tests -j2 fuzzer zstreamtest invalidDictionaries poolTests
- ./tests/fuzzer -s5346 -i1 --no-big-tests
- ./tests/zstreamtest -i3000 -s334462
- ./tests/invalidDictionaries
- timeout 20s stdbuf -oL ./tests/poolTests
