crypto: add CTR mode support
Introduce CTR mode support for the cipher APIs.
CTR mode uses a counter rather than a traditional IV.
The counter has additional properties, including a nonce
and initial counter block. We reuse the ctx->iv as
the counter for conveniences.
Both libgcrypt and nettle are support CTR mode, the
cipher-builtin doesn't support yet.
