This commit improves module loading performance by at least ~25-35%
in the module-loader benchmarks.
Some optimization strategies include:
* Try-finally/try-catch isolation
* Replacing regular expressions with manual parsing
* Avoiding unnecessary string and array creation
* Avoiding constant recompilation of anonymous functions and
function definitions within functions

Change the regular expression that recognizes “simple” JS expressions
to requiring that the full line needs to match it.
Previously, in terms like `a().b.`, `b.` would be a partial match.
This meant that completion would evaluate `b` and either fail with
a `ReferenceError` or, if `b` was some global, return the properties
of the global `b` object.

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.pause();
.. the 'pause' event will be triggered before the resume operation

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.
