Subject: Add support for dumping the status on Windows.
X-Git-Tag: fio-2.1~5

Add support for dumping the status on Windows.

Windows uses a per-user temporary directory, with the path stored in the TEMP
environment variable. Update check_status_file to check both the Unix TMPDIR
and Windows TEMP variables before falling back to /tmp.
