Remove usages of extension functions to prevent accessing to uninitialized fd(trace_marker). T-trace check whether initialing by isTagEnabled(), However, g_extension_state can permit accessing to uninitialized fd at all of write(). And, extension feature was not used anymore. Additionally, Use TTRACE_LOG() instead of fprintf(), remove useless spaces for clean codes.
