Remove the port number from IDN host names before converting to ACE #596
This is a follow-up to pull request #592 . The port number should be removed from a host name before the host name is converted to ACE. The port number is removed by parse_remote_port(), so this function must be called before fix_hostname().
Surprisingly, the tests passed before this commit, so I think that libidn actually supports port numbers in host names. But I'm not sure whether other IDN libraries (e.g. on Windows) also support port numbers.
