Proof-of-concept encoder for parallel compression.

Proof-of-concept encoder for parallel compression.
...
Add a version of the brotli encoder that compresses
each meta-block independently, only using the
original input data from previous meta-blocks
and nothing from the compressor state.
This is a proof-of-concept to show that the
current format is flexible enough to support
parallel multi-threaded compression.

Add an input block size parameter to brotli.
...
This will enable processing the input in smaller
chunks than the currently default 2MB for the
slow brotli, while still benefiting from the
larger sliding window.

Faster decoder for data with trivial context maps.
...
This makes it 20% faster when decoding data with
trivial context map (where the histogram type
depends only on the block type and not the
context).

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

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
