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).

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.

Add some missing state transitions to DecodeContextMap().
...
Update the states in DecodeContextMap to the next one,
else it would continue at the wrong spot if exactly there
the partial input is split.

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

Makefile fixes and cleanups

- Distinguish between CC/CFLAGS, CPP/CPPFLAGS and CXX/CXXFLAGS.
Do not store compiler flags in CPPFLAGS, which is for preprocessor,
and do not try to link files using a preprocessor.
- Use COMMON_FLAGS for flags that are for both C and C++.
- Drop -m64 flag which is wrong on 32-bit systems.
- Use $(MAKE) instead of make, so that parallel building works.

Fix encoder compilation error on MSVS 2010.
...
As reported by @anthrotype, log2() is missing from MSVS 2010.
This patch uses log() and a multiplication in FastLog2()
for _MSV_VER <= 1600 and uses FastLog2() in literal_cost.cc
instead of log2().
