Subject: [PATCH] Update to use SSL_F_SSL_CTX_USE_CERTIFICATE_FILE and
SSL_CTX_clear_extra_chain_certs
Patch updated by Sebastian Andrzej Siewior <sebastian@breakpoint.cc>,
with description:
SSL_F_SSL_CTX_USE_CERTIFICATE_FILE and
SSL_CTX_clear_extra_chain_certs was around in openssl since before
they forked it. So with this patch it should work with their
libressl, libssl 1.0.2 and 1.1.
