BROTLI_SHARED_DICTIONARY_SERIALIZED enum value is a part of API,
but it should not be used (will cause failures).
Changing how serialized dictionaries work won't be considered as an API change, until this feature is enabled.
Enabling this feature in the future will be considered as a "compatible" change.

Update:
* Bazel: fix MSVC configuration
* C: common: extended documentation and helpers around distance codes
* C: common: enable BROTLI_DCHECK in "debug" builds
* C: common: fix implicit trailing zero in `kPrefixSuffix`
* C: dec: fix possible bit reader discharge for "large-window" mode
* C: dec: simplify distance decoding via lookup table
* C: dec: reuse decoder state members memory via union with lookup table
* C: dec: add decoder state diagram
* C: enc: clarify access to static dictionary
* C: enc: improve static dictionary hash
* C: enc: add "stream offset" parameter for parallel encoding
* C: enc: reorganize hasher; now Q2-Q3 require exactly 256KiB
to avoid global TCMalloc lock
* C: enc: fix rare access to uninitialized data in ring-buffer
* C: enc: reorganize logging / checks in `write_bits.h`
* Java: dec: add "large-window" support
* Java: dec: improve speed
* Java: dec: debug and 32-bit mode are now activated via system properties
* Java: dec: demystify some state variables (use better names)
* Dictionary generator: add single input mode
* Java: dec: modernize tests
* Bazel: js: pick working commit for closure rules

* Verbose CLI + start pulling "Shared-Brotli"
* vesbose CLI output; fix #666
* pull `SHIFT` transforms; currently this is semantically dead code;
later it will be used by "Shared-Brotli"

* 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.
