up to that fact and revert to their recommended match of BSD-2-Clause.

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.

When a dynamic NSS module is built and linked against a thread
library, it may pull in that thread library at run time. If the
process started out single-threaded, this could cause attempts to
release locks that do not exist. Guard against this possibility by
checking __isthreaded before invoking thread primitives.

A similar problem remains if the process is linked against one thread
library, but the NSS module is linked against another. This can only
be avoided by careful design of the NSS module.
