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.

The doc says the debugger is and also isn't full-featured. Even if the
sentences are talking about different things, it's confusing.
`full-featured` seems superfluous in the first sentence anyway, so
remove it. Remove a superfluous `simple` while we're at it.

Add example to show what running Node.js with `--inspect`

Some IDEs do not show the link when running with `--inspect`.
This example hints to what the full output looks like.

Use blockquotes instead of code blocks for stability markers in
the docs. Doing that:
- Makes the makers appear correctly when viewed e.g. on github.
- Allows remark-lint rules like `no-undefined-references` to work
properly (https://github.com/nodejs/node/pull/7729).

This change introduces experimental v8-inspector support. This brings
the DevTools debug protocol allowing Node.js to be debugged with
Chrome DevTools native, or through other debuggers supporting that
protocol.
Partial WebSocket support, to the extent required by DevTools, is
included. This is derived from the implementation in Blink.
v8-inspector support can be disabled by the --without-inspector
configure flag.

This commit replaces multiple usages of `function(){}` with ES2015
arrow functions in places it was forgotten earlier. The goal is to
make the docs more consistent since other functions were already
replaced with ES2015 arrows.
In addition, it fixes invalid syntax in modules.markdown to valid
syntax as well as remove `var self = this` pattern usages in the code
where they are now possible to avoid through arrow functions.

This changes the code blocks from 4-space indentation to ``` fences for
better syntax highlighting and future linting support. Minor On-the-fly
changes for typos and highlight breaking markdown have been made.
JSON-Style objects have been changed so their closing bracket is
on the same line as the opening one.
Known issues:
* Not every JSON / object notation has been improved. Should
make another run for this.
* Some example functions break hightlighting due to various
combinations of brackets. However changing them means leaving
the code style.

In debugger, the usage of `repl` very ugly. I'd like there is a `p`
like gdb. So the `exec` is coming.
Usage:
```
$ ./iojs debug ~/git/node_research/server.js
< Debugger listening on port 5858
connecting to 127.0.0.1:5858 ... ok
break in /Users/jacksontian/git/node_research/server.js:1
> 1 var http = require('http');
2
3 http.createServer(function (req, res) {
debug> exec process.title
/Users/jacksontian/git/io.js/out/Release/iojs
debug>
```
And the `repl`:
```
debug> repl
Press Ctrl + C to leave debug repl
> process.title
'/Users/jacksontian/git/io.js/out/Release/iojs'
debug>
(^C again to quit)
```
The enter and leave debug repl is superfluous.

When developer calls setBreakpoint with an unknown script name,
we convert the script name into regular expression matching all
paths ending with given name (name can be a relative path too).
To create such breakpoint in V8, we use type `scriptRegEx`
instead of `scriptId` for `setbreakpoint` request.
To restore such breakpoint, we save the original script name
send by the user. We use this original name to set (restore)
breakpoint in the new child process.
