[PATCH] fuse: update userspace interface to version 7.8

Add a flag to the RELEASE message which specifies that a FLUSH operation
should be performed as well.  This interface update is needed for the FreeBSD
port, and doesn't actually touch the Linux implementation at all.

Also rename the unused 'flush_flags' in the FLUSH message to 'unused'.
