SECURITY
- python: added Decompressor::can_accept_more_data method and optional
  output_buffer_limit argument Decompressor::process;
  that allows mitigation of unexpectedly large output;
  reported by Charles Chan (https://github.com/charleswhchan)
Added
- decoder / encoder: added static initialization to reduce binary size
- python: allow limiting decoder output (see SECURITY section)
- CLI: brcat alias; allow decoding concatenated brotli streams
- kt: pure Kotlin decoder
- cgo: support "raw" dictionaries
- build: Bazel modules
Removed
- java: dropped finalize() for native entities
Fixed
- java: in compress pass correct length to native encoder
Improved
- build: install man pages
- build: updated / fixed / refined Bazel buildfiles
- encoder: faster encoding
- cgo: link via pkg-config
- python: modernize extension / allow multi-phase module initialization
Changed
- decoder / encoder: static tables use "small" model (allows 2GiB+ binaries)

SECURITY: decoder: fix integer overflow when input chunk is larger than 2GiB (CVE-2020-8927)

Other changes:
- add support WASM (emscripten) build
- brotli -v now reports raw / compressed size
- build files / docs maintenance
- reduce sources tarball size
- decoder: minor speed / memory usage improvements
- encoder: fix rare access to uninitialized data in ring-buffer
- encoder: improve support for platforms that does not have log2
- encoder: better support for MSVC (replacement for __builtin_clz and __builtin_ctzll
- python: decompress now reports error if there is unused after the end of compressed input
