Adds Buffer.prototype.swap16() and Buffer.prototype.swap32()
methods that mutate the Buffer instance in-place by swapping the
16-bit and 32-bit byte-order.

Example:

```js
const buf = Buffer([0x1, 0x2, 0x3, 0x4]);
buf.swap16();
console.log(buf);
  // prints Buffer(0x2, 0x1, 0x4, 0x3);

buf.swap32();
console.log(buf);
  // prints Buffer(0x3, 0x4, 0x1, 0x2);
```

* npm: Upgrade to v3.8.3. Fixes a security flaw in the use of
authentication tokens in HTTP requests that would allow an attacker to
set up a server that could collect tokens from users of the command-line
interface. Authentication tokens have previously been sent with every
request made by the CLI for logged-in users, regardless of the destination
of the request. This update fixes this by only including those tokens
for requests made against the registry or registries used for the
current install. (Forrest L Norvell)
