*Boris Pismenny, John Baldwin and Andrew Gallatin*
* The signature of the `copy` functional parameter of the
EVP_PKEY_meth_set_copy() function has changed so its `src` argument is
now `const EVP_PKEY_CTX *` instead of `EVP_PKEY_CTX *`. Similarly
the signature of the `pub_decode` functional parameter of the
EVP_PKEY_asn1_set_public() function has changed so its `pub` argument is
now `const X509_PUBKEY *` instead of `X509_PUBKEY *`.
*David von Oheimb*
* The error return values from some control calls (ctrl) have changed.
One significant change is that controls which used to return -2 for
invalid inputs, now return -1 indicating a generic error condition instead.
