From 8349ff1ec3d001aa85cc94a9004509cca8ebf036 Mon Sep 17 00:00:00 2001
From: Rosen Penev <rosenp@gmail.com>

Subject: [PATCH] crypto: Fix compilation for OpenSSL without deprecated
APIs
Added missing bn.h include.
Made engine.h include conditional, otherwise it would fail.
DSA_generate_parameters was deprecated long before 1.1.0.
