tor/changes/ticket13802

  o Minor features (testing):
    - Add a general event-tracing instrumentation support to Tor.  This
      subsystem will enable developers and researchers to add fine-grained
      instrumentation to their Tor instances, for use when examining Tor
      network performance issues.  There are no trace events yet, and
      event-tracing is off by default unless enabled at compile time.
      Implements ticket 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()".
