Update: * Bazel: fix MSVC configuration * C: common: extended documentation and helpers around distance codes * C: common: enable BROTLI_DCHECK in "debug" builds * C: common: fix implicit trailing zero in `kPrefixSuffix` * C: dec: fix possible bit reader discharge for "large-window" mode * C: dec: simplify distance decoding via lookup table * C: dec: reuse decoder state members memory via union with lookup table * C: dec: add decoder state diagram * C: enc: clarify access to static dictionary * C: enc: improve static dictionary hash * C: enc: add "stream offset" parameter for parallel encoding * C: enc: reorganize hasher; now Q2-Q3 require exactly 256KiB to avoid global TCMalloc lock * C: enc: fix rare access to uninitialized data in ring-buffer * C: enc: reorganize logging / checks in `write_bits.h` * Java: dec: add "large-window" support * Java: dec: improve speed * Java: dec: debug and 32-bit mode are now activated via system properties * Java: dec: demystify some state variables (use better names) * Dictionary generator: add single input mode * Java: dec: modernize tests * Bazel: js: pick working commit for closure rules
