QXmlStreamReader reports incorrect line number

QXmlStreamReader::lineNumber() reports the incorrect line number when the XML file is encoded with \r newline notations.

This makes troubleshooting errors very confusing, depending on which text editor the user selects to open the XML file.

See attached XML files for examples, "cr-only" always reports the same line number, while "crlf" reports the correct line number while parsing.

I opened the underlying QFile with QIODevice::ReadOnly | QIODevice::Text modes, if that's relevant.

I tested on Windows 10x64 with Qt 5.11.1. I have not tested more recent versions, but I didn't see it in subsequent release notes.
