Hi ports --

Attached is an update to Stockfish.
Release notes: https://github.com/official-stockfish/Stockfish/releases/tag/sf_12

Stockfish has moved to a new neural-net based evaluator. However, the
neural net support code is not available with the tarball. So we have
to the do the same trick as with RStudio, since GH_* and MASTER_SITES
can't live together in one port.

I am able to have SCID play a stockfish vs. stockfish game.
I am not sure how performant stockfish 12 will be on !amd64. Testing
would be appreciated on other platforms.

OK?
