Al Stone edb6c78416 Update to upstream 20200925 version
This update also means a major update for all of the big-endian patching
that has been done.  The older mechanism was getting to unwieldy to keep
maintained, and too sensitive to upstream changes.  Hence, redid all of
the old patches, and took the opportunity to make them more amenable to
change over time.  Ultimately, the goal is to have upstream accept these
in some form.
