Comment (by yawning):

 First cut: https://github.com/Yawning/tor/compare/evp_digests

 Notes:
  * Not ready yet (compiles and unit tests pass).
  * `crypto_digest_assign` is probably uglier than it needs to be.
  * Someone should figure out a good criteria for "use EVP vs the raw SHA
 interface" that can be ran at runtime.  If it were up to me, I would rip
 the old code out and always use the EVP interface, since it's simpler (and
 would make fixing the ugly dead easy...).

 It's `lorax` tagged because this is about as much time as I feel like
 spending on it right now.
