 src: add tracing controller 
This commit adds support for trace-event tracing to Node.js. It provides
a mechanism to centralize tracing information generated by V8, Node
core, and userspace code. It includes:

 - A trace writer responsible for serializing traces and cycling the
   output files so that no individual file becomes to large.
 - A buffer for aggregating traces to allow for batched flushes.
 - An agent which initializes the tracing controller and ensures that
   trace serialization is done on a separate thread.
 - A set of macros for generating trace events.
 - Tests and documentation.

Tracing

Trace Event provides a mechanism to centralize tracing information generated by V8, Node core, and userspace code.

Tracing can be enabled by passing the --trace-events-enabled flag when starting a Node.js application.

The set of categories for which traces are recorded can be specified using the --trace-event-categories flag followed by a list of comma separated category names. By default the node and v8 categories are enabled.

node --trace-events-enabled --trace-event-categories v8,node server.js

Running Node.js with tracing enabled will produce log files that can be opened in the chrome://tracing tab of Chrome.
