I'm still not happy.

For one I still see no reason to merge this broken ACL model at all.
It provides our actualy Linux users no benefit at all, while breaking
a lot of assumptions, especially by adding allow and deny ACE at the
same sime.

It also doesn't help with the issue that the main thing it's trying
to be compatible with (Windows) actually uses a fundamentally different
identifier to apply the ACLs to - as long as you're still limited
to users and groups and not guids we'll still have that mapping problem
anyway.

But besides that fundamental question on the purpose of it I also
don't think the code is suitable, more in the individual patches.
