Update from 1.0.7 to 1.0.9.
<Security note>
Please consider updating brotli to version 1.0.9 (latest).
Version 1.0.9 contains a fix to "integer overflow" problem. This
happens when "one-shot" decoding API is used (or input chunk for
streaming API is not limited), input size (chunk size) is larger
than 2GiB, and input contains uncompressed blocks. After the
overflow happens, `memcpy` is invoked with a gigantic `num`
value, that will likely cause the crash.
