Claudio's raw SHA-512 formats are renamed to -ng again, and Myrice's 
formats are now back. I updated them to latest "standards" (don't build 
until reset(), latest auto-tune and so on). I'm pretty sure the #676 bug 
was squashed in the process.

I haven't touched the kernels yet, they look like reference code. 
Probably plenty of low hanging fruit there.
