Move the core Poly1305 routines shared between the generic Poly1305 shash driver and the Adiantum and NHPoly1305 drivers into a separate library so that using just this pieces does not pull in the crypto API pieces of the generic Poly1305 routine. In a subsequent patch, we will augment this generic library with init/update/final routines so that Poyl1305 algorithm can be used directly without the need for using the crypto API's shash abstraction.

ChaCha library interface that require the generic code as a

fallback, e.g., for SIMD implementations. If no arch specific

Enable the ChaCha library interface. This interface may be fulfilled

by either the generic implementation or an arch-specific one, if one

is available and enabled.
