  o Code simplification and refactoring:
    - Unconditionally use OpenSSL's AES implementation instead of our
      old built-in one. OpenSSL's AES has been better for a while, and
      relatively few servers should still be on any version of OpenSSL
      that doesn't have good optimized assembly AES.

  o Major features:
    - Use OpenSSL's EVP interface for AES encryption, so that all
      AES operations can use hardware acceleration (if present).
      Resolves issue #4442.
Dump our internal AES implementation This thing was pretty pointless on versions of OpenSSL 0.9.8 and later, and almost totally pointless on OpenSSL 1.0.0. Also, favor EVP by default, since it lets us get hardware acceleration where present. (See issue 4442) 2011-11-09 04:51:59 +01:00			`o Code simplification and refactoring:`
