I implemented this as a module for myself, but it's something I could easily adapt to being a configurable option in the core SSL module.

Would it make sense to have a setting that changed the output? X509_NAME_print_ex accepts various flags to control the output (the old format, RFC 2253, etc). If it's worth doing as an option, I'll put together a changeset for ngx_http_ssl_module.

Format of the $ssl_client_s_dn and $ssl_client_i_dn variables was changed in 56d6bfe6b609 to follow RFC 2253 (RFC 4514), available in 1.11.6.
