New Android UCI engine: armFish 2017.08.XX

Androiders, especially the users of ARM cpu's must thank Lyudmil Antonov for making the mighty assembly port of Stockfish available for arm cpu's. Assembly builds must run the fastest possible by definition, even faster than Cfish.

It was indeed a hard task bearing in mind that even porting C++ code to Android requires a lot of knowledge about the software to be used to compile and also a good practice of several Windows and Android libraries.

Working with assembly code is even more difficult because of the primitive level of the language.  It's the least human environment for a programmer. The only reason to prefer the native assembly can be nothing but speed, which is the exact case of a chess engine. Congrats to LA for succeeding in this insane mission!

There are many builds LA released so far. You can find links to each of them below. The recent ones come with Syzygy tablebase support as well. Yummy!

The only bad news about armFish is that the builds are made for arm8 64-bit devices only.
