DSA_generate_parameters() was deprecated in 2002. I removed most API
wrapped in OPENSSL_NO_DEPRECATED, but some of it was blocked since it was
still used. rust-openssl recently fixed their "enhanced DSA support" to
use non-deprecated API, so we can remove this API now, that is to say,
once libkeynote is fixed.

Of course, the _ex() API is annoying in that you need to allocate the
DSA up front yourself.
