Brotli custom LZ77 dictionary support.
...
Adds functions to prepend such dictionary to the
encoder and decoder, and twiddles their internal
parameters to do as if that was a previous part of
the input. This dictionary is just a prefilled LZ77
window, it is not related to the built in transformable
brotli dictionary.

Speed and memory usage improvements for the decoder.
...
* Change order of members of bit reader state structure.
* Remove unused includes for assert. Add BROTLI_DCHECK
macros and use it instead of assert.
* Do not calculate nbits in common case of ReadSymbol.
* Introduce and use PREDICT_TRUE / PREDICT_FALSE macros.
* Allocate less memory in the brotli decoder if it knows
the result size beforehand. Before this, the decoder
would always allocate 16MB if the encoder annotated the
window size as 22 bit (which is the default), even if the
file is only a few KB uncompressed. Now, it'll only
allocate a ringbuffer as large as needed for the result file.
But only if it can know the filesize, it's not possible
to know that if there are multiple metablocks or too large
uncompressed metablock.
