The cache is hidden from userland applications because it has been

All the callback functions in `fs` module are supposed to be executed
with no context (`this` value should not be a valid object). But
`mkdtemp`'s callback will have the `FSReqWrap` object as the context.
Sample code to reproduce the problem
'use strict';
const fs = require('fs');
fs.mkdtemp('/tmp/abcd', null, function() {
console.log(this);
});
This would print
FSReqWrap { oncomplete: [Function] }

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.

These changes affect the following functions and their synchronous
counterparts:
* fs.readFile()
* fs.writeFile()
* fs.appendFile()
If the first parameter is a uint32, it is treated as a file descriptor.
In all other cases, the original implementation is used to ensure
backwards compatibility. File descriptor ownership is never taken from
the user.
The documentation was adjusted to reflect these API changes. A note was
added to make the user aware of file descriptor ownership and the
conditions under which a file descriptor can be used by each of these
functions.
Tests were extended to test for file descriptor parameters under the
conditions noted in the relevant documentation.
