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.

This fixes CVE-2010-0740 which only affected -CURRENT (OpenSSL 0.9.8m)
but not -STABLE branches.
I have not yet been able to find out if CVE-2010-0433 impacts FreeBSD.
This will be investigated further.

This also "reverts" some FreeBSD local changes so we should now
be back to using entirely stock OpenSSL. The local changes were
simple $FreeBSD$ lines additions, which were required in the CVS
days, and the patch for FreeBSD-SA-09:15.ssl which has been
superseded with OpenSSL 0.9.8m's RFC5746 'TLS renegotiation
extension' support.
