Verbose CLI + start pulling "Shared-Brotli" (#722)
* 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"

Update (#643)
Update
 * make the zopflification aware of `NDIRECT`, `NPOSTFIX`
   (better compression in `font` mode)
 * add small and simple decoder tool
 * fix typo
 * Java: wrapper: make decoder channel more async-friendly

Ramp up version to 1.0.3 / 1.0.3

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.
