Fix leak of file descriptors in QTemporaryFile
Using setFileName in QFile::copy (introduced recently) has a nasty side-effect of leaking file descriptors in QTemporaryFile. This happens because the code assumes the file has been closed. In QTemporaryFile, we need to explicitly call native file engine close. Test case by Thiago. Bug report from Arora developers. Reviewed-by: thiago
