Update common, decoder, encoder, java (#520)
Common:
* wrap dictionary data into `BrotliDictionary` structure
* replace public constant with getter `BrotliGetDictionary`
* reformat dictionary data
Decoder:
* adopt common changes
* clarify acceptable instance usage patterns
* hold reference to dictionary in state
Encoder:
* adopt common changes
* eliminate PIC spots in `CreateBackwardReferences`
* add per-chunk ratio guards for q0 and q1
* precompute relative distances to avoid repeated calculations
* prostpone hasher allocation/initialization
* refactor Hashers to be class-like structure
* further improvements for 1MiB+ inputs
* added new hasher type; made hashers more configurable
Java:
* Pull byte->int magic to `IntReader` from `BitReader`

Update encoder (#504)
* pull `BROTLI_MAX_BACKWARD_LIMIT` to constants
* split generic and Zopfli backward references code
* pull hashers init and stitch invocation to encoder
* make `dictionary_hash` a compilation unit
* add `size hint` parameter
* add new hasher
* use `size hint` to pick new hasher for q4
* modernize clz guard (fix #495)
* move `hash to binary tree` to separate file
* add `Initialize` and `Cleanup` to all hashers
* do not raise OOM if malloc(0) == NULL (fix #500)

Update encoder
* move `common/port.h` to `includes/port.h`
* replace magic more magic numbers with constants
* artificially limit window size to 2^18 for quality 0 and 1
* use fixed shifts for quality 0 and 1 hashes
* removed `BrotliEncoderWriteMetadata`
* added `BROTLI_OPERATION_EMIT_METADATA` instead
* deprecated low-level API
* fixed MSVC warnings

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

Add two more fast modes to the brotli compressor.
The new modes process the input data in independent blocks,
using backward references only from within an input block.
The new modes can be used by specifying quality 0 or quality 1,
the old quality 1 and quality 2 modes are renamed quality 2 and
quality 3, respectively, and the old quality 3 mode is removed.
