The socket list module (used by child_process) currently uses the
`var self = this;` pattern for context in several places, this PR
replaces this with arrow functions or passing a parameter in where
appropriate.
Note that the `var self = this` in the _request is intentioanlly
left in place since it is not trivial to refactor it and the current
pattern isn't bad given the use case.

Introduce `--no-browser-globals` configure flag. With this flag set, following
globals won't be exported:
- `setTimeout`, `clearTimeout`, `setInterval`, `clearInterval`,
`setImmediate`, `clearImmediate`
- `console`
These are provided by the DOM implementation in browser, so the
`--no-browser-globals` flag may be helpful when embedding node.js within
chromium/webkit.

This makes several changes:
1. Allow path/filename to be passed in as a Buffer on fs methods
2. Add `options.encoding` to fs.readdir, fs.readdirSync, fs.readlink,
fs.readlinkSync and fs.watch.
3. Documentation updates
For 1... it's now possible to do:
```js
fs.open(Buffer('/fs/foo/bar'), 'w+', (err, fd) => { });
```
For 2...
```js
fs.readdir('/fs/foo/bar', {encoding:'hex'}, (err,list) => { });
fs.readdir('/fs/foo/bar', {encoding:'buffer'}, (err, list) => { });
```
encoding can also be passed as a string
```js
fs.readdir('/fs/foo/bar', 'hex', (err,list) => { });
```
The default encoding is set to UTF8 so this addresses the
discrepency that existed previously between fs.readdir and
fs.watch handling filenames differently.

In several places throughout the code we write directly to stderr
to report warnings (deprecation, possible eventemitter memory leak).
The current design of simply dumping the text to stderr is less
than ideal. This PR introduces a new "process warnings" mechanism
that emits 'warning' events on the global process object. These are
invoked with a `warning` argument whose value is an Error object.
By default, these warnings will be printed to stderr. This can be
suppressed using the `--no-warnings` and `--no-deprecation` command
line flags. For warnings, the 'warning' event will still be emitted
by the process, allowing applications to handle the warnings in custom
ways. The existing `--no-deprecation` flag will continue to supress
all deprecation output generated by the core lib.
The `--trace-warnings` command line flag will tell Node.js to print
the full stack trace of warnings as part of the default handling.
The existing `--no-deprecation`, `--throw-deprecation` and
`--trace-deprecation` flags continue to work as they currently do,
but the exact output of the warning message is modified to occur
on process.nextTick().
The stack trace for the warnings and deprecations preserve and point
to the correct call site.
A new `process.emitWarning()` API is provided to permit userland
to emit warnings and deprecations using the same consistent
mechanism.
Test cases and documentation are included.

Readable.resume() schedules the resume operation onto the next tick,
whereas pause() has immediate effect. This means that in a sequence
stream.resume();
stream.pause();
.. the 'pause' event will be triggered before the resume operation
is performed.
For process.stdin, we are relying on the 'pause' event to stop reading
on the underlying handle. This fix ensures that reads are started and
stopped in the same order as resume() and pause() are called.

Currently we use `{}` for the `lookup` function to find the relevant
resolver to the dns.resolve function. It is preferable to use an
object without a Object.prototype, currently for example you can do
something like:
```js
dns.resolve("google.com", "toString", console.log);
```
And get `[Object undefined]` logged and the callback would never be
called. This is unexpected and strange behavior in my opinion.
In addition, if someone adds a property to `Object.prototype` might
also create unexpected results.
This pull request fixes it, with it an appropriate error is thrown.

Based on the conversation in #4243 this implements a way to increase
and decrease the size of the thread pool used in v8.
Currently v8 restricts the thread pool size to `kMaxThreadPoolSize`
which at this commit is (4). So it is only possible to
decrease the thread pool size at the time of this commit. However with
changes upstream this could change at a later date.
If set to 0 then v8 would choose an appropriate size of the thread pool
based on the number of online processors.

[Diffie-Hellman](https://en.wikipedia.org/wiki/Diffie%E2%80%93Hellman_key_exchange#Cryptographic_explanation)
keys are composed of a `generator` a `prime` a `secret_key`
and the `public_key` resulting from the math operation:
```
(generator ^ secret_key) mod prime = public_key
```
Diffie-Hellman keypairs will compute a matching shared secret
if and only if the generator and prime match for both
recipients. The generator is usually **2** and the prime is
what is called a [Safe Prime](https://en.wikipedia.org/wiki/Safe_prime).
Usually this matching is accomplished by using
[standard published groups](http://tools.ietf.org/html/rfc3526).
We expose access those groups with the `crypto.getDiffieHellman`
function.
`createDiffieHellman` is trickier to use. The original example
had the user creating 11 bit keys, and creating random groups of
generators and primes. 11 bit keys are very very small, can be
cracked by a single person on a single sheet of paper. A
byproduct of using such small keys were that it was a high
likelihood that two calls of `createDiffieHellman(11)` would
result in using the same 11 bit safe prime.
The original example code would fail when the safe primes generated
at 11 bit lengths did not match for alice and bob.
If you want to use your own generated safe `prime` then the proper
use of `createDiffieHellman` is to pass the `prime` and `generator`
to the recipient's constructor, so that when they compute the shared
secret their `prime` and `generator` match, which is fundamental to
the algorithm.
