  o Minor features (testing):
    - Add general tracing instrumentation to Tor. For now, this subsystem is
      not being used by any part of the code, it is for future use or external
      testing that is not part of the upstream code base. Any tracing
      framework needs to be enabled at compile time. Closes #13802.
trace: Add a basic event-tracing infrastructure. This commit adds the src/trace directory containing the basics for our tracing subsystem. It is not used in the code base. The "src/trace/debug.h" file contains an example on how we can map our tor trace events to log_debug(). The tracing subsystem can only be enabled by tracing framework at compile time. This commit introduces the "--enable-tracing-debug" option that will make all "tor_trace()" function be maped to "log_debug()".
