Get rid of the diversity of names for MAC parameters

Get rid of the diversity of names for MAC parameters

The EVP_PKEY MAC implementations had a diversity of controls that were
really the same thing.  We did reproduce that for the provider based
MACs, but are changing our minds on this.  Instead of that, we now use
one parameter name for passing the name of the underlying ciphers or
digests to a MAC implementation, "cipher" and "digest", and one
parameter name for passing the output size of the MAC, "size".

Then we leave it to the EVP_PKEY->EVP_MAC bridge to translate "md"
to "digest", and "digestsize" to "size".
