BIO_get_ktls_send() and BIO_get_ktls_recv() are documented as
returning either 0 or 1. However, they were actually returning the
internal value of the associated BIO flag for the true case instead of
1.
Also trim redundant ternary operators.

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.

seeing "Could not open /dev/crypto: No such file or directory". Disable

Because there was an extra declaration in the vendor version, we locally
removed the second one in r238405 with 1.0.1c. Later, upstream fixed it in
1.0.2d but they removed the first one. Therefore, both were removed in our
version unfortunately. Now we revert to the vendor one to re-add it.

Linking with lld fails as it contains a relative address, however the data
this address is for may be relocated from the shared object to the main
executable.
Fix this by adding the hidden attribute. This stops moving this value to
the main executable. It seems this is implicit upstream as it uses a
version script.

From the OpenSSL advisory:
Andy Polyakov discovered a flaw in OpenSSL's DTLS
implementation which could lead to the compromise of clients
and servers with DTLS enabled.
DTLS is a datagram variant of TLS specified in RFC 4347 first
supported in OpenSSL version 0.9.8. Note that the
vulnerabilities do not affect SSL and TLS so only clients and
servers explicitly using DTLS are affected.
We believe this flaw will permit remote code execution.

EVP_CIPHER_CTX_key_length() should return the set key length
in the EVP_CIPHER_CTX structure which may not be the same as
the underlying cipher key length for variable length ciphers.
This fixes problems in OpenSSH using some ciphers, and possibly other
applications.
