Merge OpenSSL 3.0.9

Migrate to OpenSSL 3.0 in advance of FreeBSD 14.0. OpenSSL 1.1.1 (the
version we were previously using) will be EOL as of 2023-09-11.

Most of the base system has already been updated for a seamless switch
to OpenSSL 3.0. For many components we've added
`-DOPENSSL_API_COMPAT=0x10100000L` to CFLAGS to specify the API version,
which avoids deprecation warnings from OpenSSL 3.0. Changes have also
been made to avoid OpenSSL APIs that were already deprecated in OpenSSL
1.1.1. The process of updating to contemporary APIs can continue after
this merge.

Additional changes are still required for libarchive and Kerberos-
related libraries or tools; workarounds will immediately follow this
commit. Fixes are in progress in the upstream projects and will be
incorporated when those are next updated.

There are some performance regressions in benchmarks (certain tests in
`openssl speed`) and in some OpenSSL consumers in ports (e.g. haproxy).
Investigation will continue for these.

Netflix's testing showed no functional regression and a rather small,
albeit statistically significant, increase in CPU consumption with
OpenSSL 3.0.

Thanks to ngie@ and des@ for updating base system components, to
antoine@ and bofh@ for ports exp-runs and port fixes/workarounds, and to
Netflix and everyone who tested prior to commit or contributed to this
update in other ways.

Most of this upstream commit touched tests not included in the

OpenSSL: Support for kernel TLS offload (KTLS)

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_OPENSSL_KTLS determines if OpenSSL is built with
KTLS support. It defaults to enabled on amd64 and disabled on all
other architectures.
