Subject: [crypto] Add support for loading an alternative Engine

Add support to plug in alternative implementations for
some or all of the cryptographic operations supported by
the OpenSSL Engine API.
When configured appropriately, OpenSSL calls the engine's
implementation of these operations instead of its own.
