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.

SSLv3 has been deprecated since 2015 (and broken since 2014: "POODLE"); it
should not have shipped in FreeBSD 11 (2016) or 12 (2018). No one should use
it, and if they must, they can use some implementation outside of base.
There are three symbols removed with OPENSSL_NO_SSL3_METHOD:
SSLv3_client_method
SSLv3_method
SSLv3_server_method
These symbols exist to request an explicit SSLv3 connection to a server.
There is no good reason for an application to link or invoke these symbols
instead of TLS_method(), et al (née SSLv23_method, et al). Applications
that do so have broken cryptography.
Define these symbols for some pedantic definition of ABI stability, but
remove the functionality again (r361392) after r362620.

This define caused a couple of symbols to disappear. To keep ABI
compatibility, we are going to keep the symbols exposed, but leave SSLv3 as
not in the default config (this is what OPENSSL_NO_SSL3 achieves). The
ramifications of this is an application can still use SSLv3 if it
specifically calls the SSLv3_method family of APIs.

This is the default configuration in OpenSSL 1.1.1 already. This moves
to align with that default.

Since OpenSSL 1.1.1, the good old BSD-specific cryptodev engine has been
deprecated in favor of this new engine. However, this engine is not
throughly tested on FreeBSD because it was originally written for Linux.

Also, the author actually meant to enable it by default on BSD platforms but
he failed to do so because there was a bug in the Configure script.

Now they found that it was more generic issue.

Therefore, we need to enable this engine on head to give it more exposure.
