PHP-5.6 php://input temp files

Hi! While hunting other bugs I noticed that the temp stream for php://input stores its temp files in sys_temp_dir instead of upload_tmp_dir (of course), which might be quite unexpected and cumbersome for a sysadmin. I prepared a fix for that (tracked as bug #67551 [1]) as PR#705 [2]. If nobody objects, I'll merge it tomorrow into PHP-5.6 so it can potentially end up in RC2.
