Richard Levitte 68a51d59a2 Move providers/common/{ciphers,digests}/* to providers/implementations
The idea to have all these things in providers/common was viable as
long as the implementations was spread around their main providers.
This is, however, no longer the case, so we move the common blocks
closer to the source that use them.
