Bug 245278 - Changing to a password with a single quote does not work
    
    https://bugzilla.redhat.com/show_bug.cgi?id=245278
    
    Description: When the Admin User password is changed on the Admin
    Console, the console escapes the password then sends it to the
    Admin Server.  This patch adds the apache API ap_unescape_url to
    mod_admserv to unescape the password before handling it.  Since
    ap_unescape_url does the unescape in place, it duplicates the
    given password and escapes on the duplicated memory.
