+DSA_sign_setup() is defined only for backward binary compatibility and

+Since OpenSSL 1.1.0 the DSA type is opaque and the output of

+cause overhead, and does not affect the actual signature
+(pre-)computation.
DSA_verify() verifies that the signature B<sigbuf> of size B<siglen>
matches a given message digest B<dgst> of size B<len>.
