gluster: the glfs_io_cbk callback function pointer adds pre/post stat args
The glfs_*_async() functions do a callback once finished. This callback
has changed its arguments, pre- and post-stat structures have been
added. This makes it possible to improve caching, which is useful for
Samba and NFS-Ganesha, but not so much for QEMU. Gluster 6 is the first
release that includes these new arguments.
With an additional detection in ./configure, the new arguments can
conditionally get included in the glfs_io_cbk handler.
