John Baldwin aa906e2a49 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.

$FreeBSD$

This directory tree contains tools used for the maintenance and
testing of FreeBSD.  There is no toplevel Makefile structure since
these tools are not meant to be built as part of the standard system,
though there may be individual Makefiles in some of the subdirs.

Please read the README files in the subdirs for further information.
