BUF_MEM_grow() returns the passed length, but also zero on error. If
the passed length was zero, an extra check to see if a returned zero
was an error or not is needed.

The EVP_KDF_ definitions are no longer needed, and neither is
EVP_get_kdfbyname()
test/evp_kdf_test.c tried to use a EVP_get_kdfbyname() that was rewritten
to use EVP_KDF_fetch() without ever freeing the resulting KDF method.
It's better to refactor the test to use EVP_KDF_fetch directly.

Undo the caching scheme, pass through most controls as parameters, except
for SEED and INFO, where we keep supporting adding data through additional
ctrl calls by collecting the data, and only passing it to the EVP_KDF
before calling its derive function.

We also use this in test_tls13messages to check that the extensions we
expect to see in a CertificateRequest are there.

If a TLSv1.3 server configured to respond to the status_request extension
also attempted to send a CertificateRequest then it was incorrectly
inserting a non zero length status_request extension into that message.
The TLSv1.3 RFC does allow that extension in that message but it must
always be zero length.
In fact we should not be sending the extension at all in that message
because we don't support it.

The OpenSSL_version_num() function returns at runtime the
OPENSSL_VERSION_NUMBER of the compiled OpenSSL library. This is a
used and useful interface, and should not (at least yet) be
deprecated, we just introduced the new versioning schema, it seems
too early to deprecate the old.

The cofactor argument to EC_GROUP_set_generator is optional, and SCA mitigations for ECC currently use it. So the library currently falls back to very old SCA-vulnerable code if the cofactor is not present.
This PR allows EC_GROUP_set_generator to compute the cofactor for all curves of cryptographic interest. Steering scalar multiplication to more SCA-robust code.
This issue affects persisted private keys in explicit parameter form, where the (optional) cofactor field is zero or absent.
It also affects curves not built-in to the library, but constructed programatically with explicit parameters, then calling EC_GROUP_set_generator with a nonsensical value (NULL, zero).
The very old scalar multiplication code is known to be vulnerable to local uarch attacks, outside of the OpenSSL threat model. New results suggest the code path is also vulnerable to traditional wall clock timing attacks.

This function re-implements EVP_CIPHER_meth_free(), but has a name that
isn't encumbered by legacy EVP_CIPHER construction functionality.
We also refactor most of EVP_CIPHER_meth_new() into an internal
evp_cipher_new() that's used when creating fetched methods.
EVP_CIPHER_meth_new() and EVP_CIPHER_meth_free() are rewritten in terms of
evp_cipher_new() and EVP_CIPHER_free(). This means that at any time, we can
deprecate all the EVP_CIPHER_meth_ functions with no harmful consequence.
