Vikas Arora	e7167a2b95	Provide one entry point for backward references. ... The new method VP8LGetBackwardReferences hides internal heuristics used for choosing RLE or LZ77 based refs. - Tuned VP8LHashChainFindCopy for better compression at higher Q. - Refactored code. - Removed the unused method VP8LVerifyBackwardReferences.
