Add support for filesystem stacked read/write of files
when enabled through a userspace init option of FUSE_STACKED_IO.

When FUSE_STACKED_IO is enabled all the reads and writes
to the fuse mount point go directly to the native filesystem
rather than through the fuse daemon. All requests that aren't
read/write still go thought the userspace code.

Please write your stacked features as kernel drivers.

Could you explain in more detail? I think I don't understand either the
why, the how, or what you mean with driver in this context (not sure
which one it is).
