   * Looks okay.
   * For crypto_digest_smartlist, since it's defined to take a list of NUL-
 terminated strings, I think it makes sense to have them remain char*.

   * Wow, that's a big one...
   * In dirvote.c, since fingerprint is a hex string, it probably makes
 sense to have it stay char.
   * Otherwise looks okay.
