lib: 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.

Fix aio system call wrappers in librt.

- Update aio_return/waitcomplete wrappers for the ssize_t return type.
- Fix the aio_return() wrapper to fail with EINVAL on a pending job.
This matches the semantics of the in-kernel system call. Also,
aio_return() returns errors via errno, not via the return value.
