With this the users can distinguish between not knowing
what the input is (ddefault) and knowing that it is text,
and thus can be relied on to force some UTF-8 specific settings.

extend the range, since it has not been used

command.h and hash.h. Now they have been made the same,
also consistent with the spec (e.g. 0 means use previous dist, etc...)

Faster encoding for low quality settings.

With this commit, the encoder will skip some
compression optimization steps for quality <= 4,
which results in faster compression but higher
compressed sizes.

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.
