Summary

Mostly this is a thin shim around existing code to integrate with
enc_xform and cryptosoft (+ cryptodev).

Note that for correctness, the enc_xform specifies an API blocksize of 1
byte. This is correct, but inefficient because our cryptosoft device
passes a single block at a time to algorithms. I intend to extend the
xform API a little bit here to enable saner chunking in future work.

Fix logic error in key size validation and improve CRYPTDEBUG() while here.

Fix IV size and passthrough to underlying implementation. With this change,
cryptocheck (with added chacha20 mode, linked aginst openssl-devel 1.1 from
ports) passes.
