mod_proxy/ssl: cleanup per-request SSL configuration for recycled proxy conns. The SSL dir config of proxy/backend connections is stored in r->per_dir_config but those connections have a lifetime independent of the requests they handle. So we need to allow the external ssl_engine_set() function to reset mod_ssl's dir config in between proxy requests, or the first sslconn->dc could be used after free for the next requests. mod_proxy can then reset/reinit the request config when recycling its backend connections. * Solve a chicken and egg problem here: We need to have sslconn->dc set correctly when we want to init sslconn, but we need to allocate memory for it first.
