Added
- common: `BROTLI_BOOL`, `BROTLI_TRUE`, `BROTLI_FALSE`
- decoder: API with `BrotliDecoder` prefix instead of plain `Brotli`
- build: Bazel, CMake

Deprecated
- decoder: API with plain `Brotli` prefix

Changed
- boolean argument / result types are re-branded as `BROTLI_BOOL`

Improved
- build: reduced amount of warnings in various build environments
- encoder: faster compression
- encoder: lower memory usage

Added
- common: library has been assembled from shared parts of decoder and encoder
- encoder: C API

Removed
- encoder: C++ API

Added
- encoder: faster compression modes (quality 0 and 1)
- decoder: `BrotliGetErrorCode`, `BrotliErrorString` and
`BROTLI_ERROR_CODES_LIST`

Removed
