	evhtp_proto        evhtp_request_get_proto(evhtp_request_t *);
	evhtp_conn_t     * evhtp_request_get_conn(evhtp_request_t *);
	evhtp_hdrs_t     * evhtp_request_get_headers_in(evhtp_request_t *);
	evhtp_hdrs_t     * evhtp_request_get_headers_out(evhtp_request_t *);
	evhtp_callback_cb  evhtp_request_get_cb(evhtp_request_t *);
	void             * evhtp_request_get_cbarg(evhtp_request_t *);
	int                evhtp_request_get_sock(evhtp_request_t *);
	const char       * evhtp_request_get_path(evhtp_request_t *);
	const char       * evhtp_request_get_uri(evhtp_request_t *);
	const char       * evhtp_request_method_str(evhtp_request_t *);
	int                evhtp_request_get_matched_soff(evhtp_request_t *);
	int                evhtp_request_get_matched_eoff(evhtp_request_t *);
	int64_t            evhtp_request_get_content_length(evhtp_request_t *);

 - Better callback return error and response handling.
		* Callbacks which return an evhtp_res code now must use
      EVHTP_RES_*, where each EVHTP_RES_* definition is a HTTP
      status code. For example "return EVHTP_RES_400;" will
      send a 404 error to the client, along with terminating
      the parser.

 - All static functions prefixed with _htp_* are now just static htp_
 - Various small bugfixes.

v0.3.4
 - Added optional OpenSSL support (with optional threading abstractions).
   * In order to properly enable SSL for your server two things must happen:
     evhtp_ssl_cfg structure must be filled with your settings:

         evhtp_ssl_cfg scfg = {
             .pemfile        = ssl_pem,
             .privfile       = ssl_pem,
             .cafile         = ssl_ca,
             .ciphers        = "RC4+RSA:HIGH:+MEDIUM:+LOW",
             .ssl_opts       = <SSL SPECIFIC FLAGS>,
             .enable_scache  = 1,
             .scache_timeout = 1024,
             .scache_init    = evhtp_ssl_scache_builtin_init,
             .scache_add     = evhtp_ssl_scache_builtin_add,
             .scache_get     = evhtp_ssl_scache_builtin_get,
             .scache_del     = NULL,
         };
   * please note that .scache_init, .scache_add, .scache_get, and .scace_del
     are function points to allow for a user to define their own session cache
     mechanism. Libevhtp has a few default built-in cache functions:
      evhtp_ssl_scache_builtin_init,
      evhtp_ssl_scache_builtin_add,
      evhtp_ssl_scache_builtin_get,
      evhtp_ssl_scache_builtin_del

     Another side note here is that currently the builtin functions do not expire,
     this will be fixed in the next beta-release.

   * The second step is to enable the use of the SSL backend by calling
     evhtp_use_ssl(evhtp_t *, evhtp_ssl_cfg *);

 - Regular expression based path callback functions added:
     evhtp_set_regex_cb(evhtp_t *, "^(/path_w_regex/).*", callback, args);

     Using the case above, any path/uri in the request with /path_w_regex/*, the API
     will execute your defined callback function. The output of which is the same as
     any other defined callback.

 - Added _htp_callbacks_find_callback_woffsets(), which (if regex) will set 2 integer
   variables in the evhtp_rquest_t structure defining the beginning and end of a matched
   URI/path.

 - _htp_callback_new() has been modified to create regex based evhtp_callback_t's

 - Made the evhtp_request_t structure private, various get/set functions have been added
   to deal with the internals.

 - Modified compile to support libonigurmura, a BSD licensed cross-platform regular expression
   library. Currently this is only used to support posix regex functionality.
