Move the code around so that libc behaviour does not depend on a variable
that was supposed to be kernel-only. There should be no functional changes.

Make acl_strip_np(3) use new trivial ACL format for NFSv4 ACls (three
entries instead of six). This makes "setfacl -b" do the right thing
for ACLs on ZFS. UFS recognizes both kinds of trivial ACLs; no change
there.

First step at adopting FreeBSD to support PSARC/2010/029. This makes
acl_is_trivial_np(3) properly recognize the new trivial ACLs. From
the user point of view, that means "ls -l" no longer shows plus signs
for all the files when running ZFS v28.

Arrgh, tested wrong source tree _again_. Fix previous commit. Also,
this and previous one are MFC candidate.

Add minor optimization. It's less strict than its kernel counterpart
due to upcoming ACL changes required by the new ZFS.

Fix usage of uninitialized variable.

Fix c194955 - somehow I managed all the new files, tripling their
contents.

Add NFSv4 ACL support to libc.

This adds the following functions to the acl(3) API: acl_add_flag_np,
acl_clear_flags_np, acl_create_entry_np, acl_delete_entry_np,
acl_delete_flag_np, acl_get_extended_np, acl_get_flag_np, acl_get_flagset_np,
acl_set_extended_np, acl_set_flagset_np, acl_to_text_np, acl_is_trivial_np,
acl_strip_np, acl_get_brand_np. Most of them are similar to what Darwin
does. There are no backward-incompatible changes.
