This prefixes all crypto module loading with "crypto-" so we never run
the risk of exposing module auto-loading to userspace via a crypto API,
as demonstrated by Mathias Krause:

The specification which crypto facility is required for an algorithm is added
as a parameter to the availability check which is done before an algorithm is
registered. With this change it is easier to add new algorithms that require
different facilities.

This patch adds export/import support to sha512-s390 (which includes
sha384-s390). The exported type is defined by struct sha512_state,
which is basically the entire descriptor state of sha512_generic.
Since sha512-s390 only supports a 64-bit byte count the import
function will reject anything that exceeds that.

I missed the block size when converting sha512-s390 to shash.
