Subject: [PATCH] fuse: add setlease file operation

Add the setlease file_operation to fuse_file_operations, pointing to
generic_setlease.  A future patch will change the default behavior to
reject lease attempts with -EINVAL when there is no setlease file
operation defined. Add generic_setlease to retain the ability to set
leases on this filesystem.

As Jan pointed out in review, this patch is also needed in the
vfs-7.0.leases branch, as I missed FUSE. Can you drop this patch on top
of that branch, preferably ahead of the patch that changes
kernel_setlease()? Let me know if you'd rather I resend the whole pile.
