501cb86172 Fix build with -Wmissing-declarations.
While there, add -Wmissing-prototypes and -Wmissing-declarations
to shared.mk in order to catch similar errors in the future.

14d6ae74a9 Reorder members of the Command struct plus fix some warnings.
This may save 8 bytes of padding per Command (32 -> 24 bytes).

1bf1b0a598 Faster entropy coding phase for quality 1.
In quality 1, use static Huffman codes for distance
and command histograms with <= 128 symbols and dynamic
Huffman codes with static code length codes for the other
histograms.

667f70adcb Speedups to brotli quality 11.
* Cluster at most 64 histograms at a time in the first
    round of clustering.

  * Use a faster histogram cost estimation function.

  * Don't compute the log2(total) multiple times in the
    block splitter.

2fd80cdc9a Encoder support for new empty meta-block format.
Changed the parallel implementation to sync meta-blocks
to byte boundary by emitting empty meta-blocks.

d6d69ec4ac Add quality and lgwin to the BrotliParams.
Remove the hard-coded constants for window size
and meta-block size.

Initialize internal storage for each metablock
separately and reserve only as much as needed
for the actual input.

534654def1 Add a faster but less dense compression mode.
The new mode can be used by setting the greedy_block_split
field of BrotliParams to true.

This commit moves all the meta-block processing code
into its own library and moves the meta-block encoding
code to brotli_bit_stream.cc from encode.cc

497814eebd Remove the redundant EncodeMetaBlockHeader() function.
Use Store{Compressed,Uncompressed}MetaBlockHeader() instead.

d6d9fc60e1 Factor out serialization functions into their own file.
Create a brotli_bit_stream library that is responsible for writing
various structures (headers, Huffman codes, etc.) directly into the
bit-stream.
