  New feature: "Large Window Brotli" (#640)
  
  * New feature: "Large Window Brotli"
  
  By setting special encoder/decoder flag it is now possible to extend
  LZ-window up to 30 bits; though produced stream will not be RFC7932
  compliant.
  
  Added new dictionary generator - "DSH". It combines speed of "Sieve"
  and quality of "DM". Plus utilities to prepare train corpora
  (remove unique strings).
  
  Improved compression ratio: now two sub-blocks could be stitched:
  the last copy command could be extended to span the next sub-block.
  
  Fixed compression ineffectiveness caused by floating numbers rounding and
  wrong cost heuristic.
  
  Other C changes:
   - combined / moved `context.h` to `common`
   - moved transforms to `common`
   - unified some aspects of code formatting
   - added an abstraction for encoder (static) dictionary
   - moved default allocator/deallocator functions to `common`
  
  brotli CLI:
   - window size is auto-adjusted if not specified explicitly
  
  Java:
   - added "eager" decoding both to JNI wrapper and pure decoder
   - huge speed-up of `DictionaryData` initialization
  
  * Add dictionaryless compressed dictionary
  
  * Fix `sources.lst`
  
  * Fix `sources.lst` and add a note that `libtool` is also required.
  
  * Update setup.py
  
  * Fix `EagerStreamTest`
  
  * Fix BUILD file
  
  * Add missing `libdivsufsort` dependency
  
  * Fix "unused parameter" warning.
