Get file position when attaching an open file descriptor to QFile
This was already being done when attaching to FILE* streams. Doing the same here makes the API consistent and more usable. Namely, one can use QFile::pos() to obtain the file position. Test case verifies this doesn't break support for sequential files. More thorough test case included in large file support test. Reviewed-by: Thiago Macieira
