Abandon the auto-ENGINE /dev/crypto interface.  VIA 3des cbc receives
collateral damage.

The syncronous nature of this mechanism has hampered performance for
symmetric crypto relative to brute-force cpu. The assymetric crypto
support never really materialized in drivers.

So abandon the complexity.
ok tedu beck mikeb
some disagrement from djm but if he wants to test /dev/crypto ciphers
he should do it without this this gigantic API in the way
