fuse: allow xlators to request for direct-io-mode on virtual files
Translators like meta, create virtual files with dynamic content generated only at the time of open(). Therefore the file size returned in lookup or stat is 0 (just like files in /proc). However the VFS does not read beyond the size, and if the size is 0, no READ ever reaches gluster for that file -- unless direct-io-mode is enabled. This patch allows translators to return "direct-io-mode" flag for such 0-byte virtual files in xdata of open_cbk/create_cbk.
