libipsec: make const-correct

- add const to the appropriate places in the libipsec public API and the

libipsec: make const-correct

- add const to the appropriate places in the libipsec public API and the
relevant internal functions needed to support that.

- replace caddr_t with c_caddr_t in ipsec_dump_policy()

- update the ipsec_dump_policy manpage to use c_caddr_t (this manpage
was already wrong as it had "char *" instead of caddr_t previously).

While here, update pfkeyv2.h to not cast away const in the PFKEY_*()
macros.

This should not cause any ABI changes as the actual types have not
changed.

General further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 3-Clause license.

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.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.
