  Add compatibility with Aladdin Enterprises MD5 implementation This will be guarded by a LIBMD_MD5_ALADDIN macro check, to avoid polluting the namespace by unsuspecting code. The macro can always be defined unconditionally, and the guard could even potentially be removed in the future if required.

   * This code implements the MD5 message-digest algorithm.
   * The algorithm is due to Ron Rivest.  This code was
   * written by Colin Plumb in 1993, no copyright is claimed.
   * This code is in the public domain; do with it what you wish.
   *
   * Equivalent code is available from RSA Data Security, Inc.
   * This code has been tested against that, and is equivalent,
   * except that you don't need to include two pages of legalese
   * with every copy.
