    @bryancall It looks good. But it totally needs 3 macros like below as far 
as I tried.
    
    ```
    #define DebugHttp2Con(ua_session, fmt, ...) \
      DebugSsn(ua_session, "http2_con", "[%" PRId64 "] " fmt, 
ua_session->connection_id(), __VA_ARGS__);
    
    #define DebugHttp2StreamMsg(ua_session, stream_id, msg) \
      DebugSsn(ua_session, "http2_stream", "[%" PRId64 "] [%u]" msg, 
ua_session->connection_id(), stream_id);
    
    #define DebugHttp2StreamFmt(ua_session, stream_id, fmt, ...) \
      DebugSsn(ua_session, "http2_stream", "[%" PRId64 "] [%u]" fmt, 
ua_session->connection_id(), stream_id, __VA_ARGS__);
    ```
    
    Actually this is what we're doing in Http2ClientSession. See 
[Http2ClientSession.cc#L34-L36](https://github.com/apache/trafficserver/blob/master/proxy/http2/Http2ClientSession.cc#L34-L36).
    Is there better macros technics? Or is this just fine?

>
> 1. {{http2_cs}} debug tag is used in {{Http2ClientSession}} and 
> {{Http2ConnectionState}} classes. This sometimes makes me confused when I 
> debug HTTP/2 components.
> It is better to change debug tag of {{Http2ConnectionState}} to 
> {{http2_conn}}.
> 2. Some debug logs has stream id. It is better that other debug logs in 
> {{Http2ConnectionState}} has stream id too.
