SSL: RFC2253 compliant $ssl_client_s_dn and $ssl_client_i_dn. Originally, the variables kept a result of X509_NAME_oneline(), which is, according to the official documentation, a legacy function. It produces a non standard output form and has various quirks and inconsistencies. The RFC2253 compliant behavior is introduced for these variables. The original variables are available through $ssl_client_s_dn_legacy and $ssl_client_i_dn_legacy.
