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.

Renumber copyright clause 4

Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same

Don't leak addrinfo if ai->ai_addrlen <= minsiz test fails.

Don't leak addrinfo if ai->ai_addrlen <= minsiz test fails.

If the ai->ai_addrlen <= minsiz test fails, then freeaddrinfo()
does not get called to free the memory just allocated by getaddrinfo().
Fix by moving ai->ai_addrlen <= minsiz to a separate nested if
block, and keep freeaddrinfo() in the outer block so that freeaddrinfo()
will be called whenever getaddrinfo() succeeds.

resolver: preserve binary compatibility; reduce header pollution

In r289315, I added new fields to res_state. This broke binary
backward compatibility. It also broke some ports (and possibly
other code) by requiring the definition of time_t and struct timespec.

Fix these problems by moving the new fields into __res_state_ext.
