2017-03-06Update common, decoder, encoder, java (#520)Eugene Kliuchnikov3-3/+7
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`

2017-02-07Fix #502 decoder bug (#505)Eugene Kliuchnikov1-0/+6
Decoder may have produced invalid output if: * at offset 0..3 dictionary word with index 3..0 for some length N is used and distance is encoded with direct distance code 0, and * at least one of next 4 commands use value from distance ringbuffer
