rGaa906e2a4957: OpenSSL: Support for kernel TLS offload (KTLS)

Summary

This merges upstream patches from OpenSSL's master branch to add
KTLS infrastructure for TLS 1.0-1.3 including both RX and TX
offload and SSL_sendfile support on both Linux and FreeBSD.

Note that TLS 1.3 only supports TX offload.

A new WITH/WITHOUT_KTLS determines if OpenSSL is built with KTLS
support. It defaults to enabled.

Test Plan

did simple testing of openssl s_server with TLS 1.2 with an AES-GCM cipher suite and both TX and RX were offloaded

I have not yet regenerated the affected manual pages as I wasn't sure how to do that (the notes in FreeBSD-upgrade in the vendor tree say to regen, but don't give a command). I also haven't regenerated openssl.conf.h.in though I don't think it is affected? We would want to regen it with 'enable-ktls' passed to OpenSSL's configure script though. If we wanted the KTLS bits to be under an option (e.g. MK_KTLS) then we could have OPENSSL_NO_KTLS in openssl.conf.h.in be dependent on that option similar to the way NO_ASM is handled in openssl.conf.h.in I believe.

Note that we (Netflix) have been running this patch in evolving state since 2017 in production.

We might consider only enabling this by default on amd64 to match what we've done with 'options KERN_TLS' in GENERIC.

LGTM

I will probably split this up into a few commits. I will certainly regen src.conf.5 as a separate commit. I will probably also do the manpage regen as a separate commit.

I've pushed an updated branch with the commits split out here: https://github.com/freebsd/freebsd-src/compare/main...bsdjhb:ktls_openssl
