brotli/c/enc/cluster.h
Evgenii Kliuchnikov a8f5813b84 Update
Documentation:
  - add note that brotli is a "stream" format, not an archive-like
  - regenerate .1 with Pandoc
Build:
  - drop legacy "BROTLI_BUILD_PORTABLE" option
  - drop "BROTLI_SANITIZED" definition
Code:
  - c: comb includes
  - c/enc: extract encoder state into separate header
  - c/enc: drop designated q10 codepath
  - c/enc: dealing better with flushing of empty stream
  - fix MSVC compilation
API:
  - py: use library version instead of one in version.h
  - c: add plugable API to report consumed input / produced output
  - c/java: support "lean" prepared dictionaries (without copy of source)
