Remove the combine option. This was used for compatibility with some
non standard behaviour in ancient versions of OpenSSL: specifically
the X509_ATTRIBUTE and DSAPublicKey handling. Since these have now
been revised it is no longer needed.

DSA public keys could exist in two forms: a single Integer type or a
SEQUENCE containing the parameters and public key with a field called
"write_params" deciding which form to use. These forms are non standard
and were only used by functions containing "DSAPublicKey" in the name.

Simplify code to only use the parameter form and encode the public key
component directly in the DSA public key method.
