  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)
