libc: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using mis-identified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

acl_strip_np, acl_get_brand_np. Most of them are similar to what Darwin
does. There are no backward-incompatible changes.

Minor fixes to library interface to improve POSIX.1e compliance. This
adds _np to a couple of function prototypes that provided more broad/useful
interfaces than POSIX.1e interfaces included.

Also, move from using a heuristic to identify POSIX.1e-semantic ACLs to
using different ACL types for non-POSIX.1e ACLs. This should clean up the
existing fuzzy logic that determined when acl_sort() should be applied
before kernel submission.
