Hash :b3d3723f Message :Add "zopfli"-style backward reference search to brotli.
This commit adopts the backward reference search algorithm
from the zopfli project (see https://github.com/google/zopfli)
to brotli.
This slower backward reference search is run only in quality 11
and it runs two iterations of entropy cost modeling and
shortest path search.
As a result, the original backward reference search function can
be simplified a bit, since we can remove some heuristics that were
replaced with the zopfli-style search.
