*) Corrected the documentation of the return values from the EVP_DigestSign*
set of functions. The documentation mentioned negative values for some
errors, but this was never the case, so the mention of negative values
o Removed the heartbeat message in DTLS feature.
o Added EVP_KDF, an EVP layer KDF API, and a generic EVP_PKEY to EVP_KDF
bridge.
+ o All of the low level MD2, MD4, MD5, MDC2, RIPEMD160, SHA1, SHA224,
