13.3 relnotes: first draft

[karels]

Summary

Flesh out the 13.3 release notes with information from git commits
with Relnotes: yes, entries in RELNOTES, and some information from
UPDATING. Portions sent to involved parties for review.

John, I included you specifically for the last section on 32-bit systems, but I think you have at least one other item in here.

Ed, you have a number of items; you could search for FreeBSD Foundation.

"following minor releases" maybe, to make it less ambiguous?

I'll let John deal with this section; sounds fine to me though.

Various updates from out-of-band correspondence with involved parties;
update zlib revision; a few additions including clang.

New changes LGTM, one comment from @pauamma_gundo.com on pf syntax remains open.

Not being conversant in pf rules, I'm checking this with the original author.

Seems fine to me, but adding "minor" is also fine with me.
