Nikhilesh Reddy 759832b661 fuse: Add support for shortcircuited read/write for files ...

Add support for shortcircuited read/write for files
when enabled through a userspace init option of
FUSE_PASSTHROUGH.

When FUSE_PASSTHROUGH 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 requsts that aren't
read/write still go thought the userspace code.

This allows for significantly better performance on read and writes
and the difference between fuse and the native lower filesystem is
negligible.
