fuse: Use the high bit of request ID for indicating resend requests
Some FUSE daemons want to know if the received request is a resend
request. The high bit of the fuse request ID is utilized for indicating
this, enabling the receiver to perform appropriate handling.
The init flag "FUSE_HAS_RESEND" is added to indicate this feature.
