Hi Paul,

Thanks for doing that.

FYI, cp in particular needs working ACL-detection support, too.
The problem is when a Linux system mounts a ZFS file system.
Then, there is no acl_trivial function, yet the number of
ACL entries is 4, and the ACL *is* trivial.

That's when we need an acl_trivial replacement function.
Without it, cp -p produces diagnostics when failing to copy
nonexistent ACLs on such a set-up.
