Subject: [PATCH] OpenSSL: Apply connection flags before reading certificates
This is needed to be able to drop the OpenSSL security level, if
necessary, for cases where old certificates (e.g., something using SHA-1
signatures) are still needed. openssl_ciphers="DEFAULT@SECLEVEL=0" can
achieve this, but only if applied before attempting to load the
certificates.
