Commit fe0a0b59, which moved code to do MD5 authentication to a separate CheckMD5Auth() function, left behind a comment that really belongs inside the function, too. Also move the check for db_user_namespace inside the function, seems clearer that way. Now that the md5 salt is passed as argument to md5_crypt_verify, it's a bit silly that it peeks into the Port struct to see if MD5 authentication was used. Seems more straightforward to treat it as an MD5 authentication, if the md5 salt argument is given. And after that, md5_crypt_verify only used the Port argument to look at port->user_name, but that is redundant, because it is also passed as a separate 'role' argument. So remove the Port argument altogether.
