Document DSAparams_dup(3). It is in <openssl/dsa.h> and documented

by OpenSSL, so it is clearly public.

OpenSSL documents it in doc/man3/X509_dup.pod, but with wrong header
file, wrong prototype, and misleading description.

While here, fix the wrong d2i_DSA_SIG(3) return type and document
those RETURN VALUES that i could easily figure out.
