This updated the generic SHA-512 implementation to use the generic shared SHA-512 glue code. It also implements a .finup hook crypto_sha512_finup() and exports it to other modules. The import and export() functions and the .statesize member are dropped, since the default implementation is perfectly suitable for this module.
