Integrate SHA2-224 with userspace components
The double compilation of the kernel sources in libmd and libcrypt is baffling, but add yet another define hack to prevent duplicate symbols. Add documentation and SHA2-224 test cases to libmd. Integrate with the md5(1) command, document, and add more test cases; self-tests pass.
