Section 9.5 of RFC 6458 (SCTP Socket API) requires that
sctp_getladdrs() returns 0 in case the socket is unbound. This
is the cause of reporting 0 addresses. So don't indicate an
error, just report this case as required.

Cleanup the defintion of struct sctp_getaddresses. This stucture
is used by the IPPROTO_SCTP level socket options SCTP_GET_PEER_ADDRESSES
and SCTP_GET_LOCAL_ADDRESSES, which are used by libc to implement
sctp_getladdrs() and sctp_getpaddrs().
These changes allow an old libc to work on a newer kernel.

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.
