* condense printf in port.h; use BROTLI_LOG everywhere
* mark non-exported functions with BROTLI_INTERNAL
* use BROTLI_DUMP instead of (void)(BROTLI_FAILURE())
* fix problems with CustomDictionary
* make decode.h independent of state.h
* fix "double-new-lines"
* fix some strict compilation warnings
* fix bro.cc compilation for MSVS
* added compressor.h as a replacement for encode.h + streams.h
While there, add -Wmissing-prototypes and -Wmissing-declarations
to shared.mk in order to catch similar errors in the future.

Instead of returning false, if it is called with no
new input for a non-last block, just check if it has
any already processed data to flush, and if not,
return true with empty output.
The new modes process the input data in independent blocks,
using backward references only from within an input block.
The new modes can be used by specifying quality 0 or quality 1,
the old quality 1 and quality 2 modes are renamed quality 2 and
quality 3, respectively, and the old quality 3 mode is removed.
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.
* Remove default constructors.
* Initialize bit_cost in histogram.Clear().
* Check fseek result in FileSize.
* Replace malloc in BrotliFileIn constructor with "new".
* Catch bad_alloc in bro tool.
These affected only quality 11, and now it does not make sense
to disable block splitting or context modeling because most of
the time is spent in zopfli anyway.
Now all speed vs size compromises are controlled by the quality param.
This is used for quality 11, for qualities <= 9 we already
have a simpler hash table.
The static data size is 252 kB, and this removes the
need to initialize a huge hash map at startup, which was
the reason why transforms had to be disabled by default.
In comparison, the static dictionary itself is 120 kB.
This supports every transform, except the kOmitFirstN.
