Limit the range of the QUrlPrivate::port to -1 to 65535

The internal parser can read values outside this range (and cannot
report an error), but QUrl::port() must not return something outside
that range. The correct solution would be to report an error, like in
Qt 5, but that cannot easily be done.

The rewritten parser in Qt 5 is not affected by this issue.
