tools/brotli: improve window size autodetect (#710)
Window size is defined as:
`(1 << BROTLI_PARAM_LGWIN) - 16`
in `c/include/brotli/encode.h`
Therefore we should probably take these 16 bytes into account.
Done basic manual testing:
$ python3 -c 'print ("A"*2046)' > t
$ bazel run -- //:brotli -w 0 -f -o $(realpath t).br $(realpath ./t)
$ python3 research/brotlidump.py t.br |& fgrep WSIZE
0000 c1 1000001 WSIZE windowsize=(1<<12)-16=4080
New version properly detects window size of `4080`, while previous one used `2032`:
$ python3 research/brotlidump.py t.br |& fgrep WSIZE
0000 b1 0110001 WSIZE windowsize=(1<<11)-16=2032

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.
