md5 code can be removed
Hi, on my Solaris 11 system, the OS provides the MD5 functions, so the code in third-party/zuid/interfaces is not necessary and I don't need to complicate the license information of the package. I would expect most Linux and BSD distributions to be in a similar situation.
Here's a crude patch I use, but I guess you'd need to make it work for systems without the md5 header (Windows?) md5.patch
