staging: crypto: skein: import code from Skein3Fish.git

This is a byte-for-byte copy of the skein implementation found at:

  https://github.com/wernerd/Skein3Fish.git

Specifically, from the master branch at commit:

  00e925444c2c Merge pull request #4 from csm/master

The next commit will do the minimum necessary to build this code as a
module.

I've generated the sha256 sums of the files by:

$ (cd drivers/staging/skein; find . -type f | sort | xargs sha256sum)
