Update encoder:
* booleanification
* integer BR scores, may improve performance if FPU is slow
* condense speed-quality constants in quality.h
* code massage to calm down CoverityScan
* hashers refactoring
* new hasher - improved speed, compression and reduced memory usage for q:5-9 w:10-16
* reduced static recources -> binary size

Bug fixes for the brotli encoder.
* Fix an out-of-bounds access to depth_histo in the
bit cost calculation function.
* Change type of distance symbol to uint16_t in block
splitter, because if all postfix bits are used, there
can be 520 distance symbols.
* Save the distance cache between meta-blocks at the
correct place. This fixes a roundtrip failure that
can occur when there is an uncompressed metablock
between two compressed metablocks.
* Fix a bug when setting lgwin to 24 in the encoder parameters
It ended up making metablocks larger than 24 bits in size.
* Fix out-of-bounds memory accesses in parallel encoder.
CreateBackwardReferences can read up to 4 bytes past end of
input if the end of input is before mask.
* Add missing header for memcpy() in port.h

Updates to Brotli compression format, decoder and encoder
This commit contains a batch of changes that were made to the Brotli
compression algorithm in the last month. Most important changes:
* Fixes to the spec.
* Change of code length code order.
* Use a 2-level Huffman lookup table in the decoder.
* Faster uncompressed meta-block decoding.
* Optimized encoding of the Huffman code.
* Detection of UTF-8 input encoding.
* UTF-8 based literal cost modeling for improved
backward reference selection.

Updates to Brotli compression format, decoder and encoder
This commit contains a batch of changes that were made to the Brotli
compression algorithm in the last month. Most important changes:
* Updated spec
* Changed Huffman code length alphabet to use run length codes more
efficiently, based on a suggestion by Robert Obryk
* Changed encoding of the number of Huffman code lengths (HLEN)
* Changed encoding of the number of Huffman trees (NTREES)
* Added support for uncompressed meta-blocks

Updates to Brotli compression format, decoder and encoder
This commit contains a batch of changes that were made to the Brotli
compression algorithm in the last three weeks. Most important changes:
* Added UTF8 context model for good text compression.
* Simplified context modeling by having only 4 context modes.
* Per-block context mode selection.
* Faster backward copying and bit reading functions.
* More efficient histogram coding.
* Streaming support for the decoder and encoder.
