1. In addition to overriding the default application name,
one can now also override the configuration file name
and flags passed to CONF_modules_load_file().
2. By default we still keep going when configuration file
processing fails. But, applications that want to be strict
about initialization errors can now make explicit flag
choices via non-null OPENSSL_INIT_SETTINGS that omit the
CONF_MFLAGS_IGNORE_RETURN_CODES flag (which had so far been
both undocumented and unused).
3. In OPENSSL_init_ssl() do not request OPENSSL_INIT_LOAD_CONFIG
if the options already include OPENSSL_INIT_NO_LOAD_CONFIG.
4. Don't set up atexit() handlers when called with INIT_BASE_ONLY.
