3dbe2e03e7 Encoder implementation using input/output classes.
Add a BrotliCompress() method to the public encoder API
that uses the BrotliIn and BrotliOut classes and use
that in the 'bro' command-line tool.

Use the streaming api in BrotliCompressBuffer() and
BrotliCompressor::WriteMetaBlock().

Use the appropiate hashers for quality <= 9.

c6b9c7c5c8 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.
