Posix1e funcs in FreeBSD

[Andrew Pantyukhin]

When looking at our ACLs, and how 3d-party code might use them
(e.g. python libacl for ACL support in rdiff-backup), I see there
are missing parts. For example, acl_copy_ext/int, acl_size are
missing. These three are present in Linux.

My question is, what's the status of posix1e-related work in
FreeBSD and TrustedBSD. Is it intentionally slowed down, or will
new work be accepted? If the latter, what's the right place to
send patches to and discuss them?
