Update nodejs to 6.3.0 (#948)

### Notable changes

* **buffer**: Added `buffer.swap64()` to compliment `swap16()` & `swap32()`. (Zach Bjornson) [#7157](nodejs/node#7157)
* **build**: New `configure` options have been added for building Node.js as a shared library. (Stefan Budeanu) [#6994](nodejs/node#6994)
  - The options are: `--shared`, `--without-v8-platform` & `--without-bundled-v8`.
* **crypto**: Root certificates have been updated. (Ben Noordhuis) [#7363](nodejs/node#7363)
* **debugger**: The server address is now configurable via `--debug=<address>:<port>`. (Ben Noordhuis) [#3316](nodejs/node#3316)
* **npm**: Upgraded npm to v3.10.3 (Kat Marchán) [#7515](nodejs/node#7515) & (Rebecca Turner) [#7410](nodejs/node#7410)
* **readline**: Added the `prompt` option to the readline constructor. (Evan Lucas) [#7125](nodejs/node#7125)
* **repl / vm**: `sigint`/`ctrl+c` will now break out of infinite loops without stopping the Node.js instance. (Anna Henningsen) [#6635](nodejs/node#6635)
* **src**:
  - Added a `node::FreeEnvironment` public C++ API. (Cheng Zhao) [#3098](nodejs/node#3098)
  - Refactored `require('constants')`, constants are now available directly from their respective modules. (James M Snell) [#6534](nodejs/node#6534)
* **stream**: Improved `readable.read()` performance by up to 70%. (Brian White) [#7077](nodejs/node#7077)
* **timers**: `setImmediate()` is now up to 150% faster in some situations. (Andras) [#6436](nodejs/node#6436)
* **util**: Added a `breakLength` option to `util.inspect()` to control how objects are formatted across lines. (cjihrig) [#7499](nodejs/node#7499)
* **v8-inspector**: Experimental support has been added for debugging Node.js over the inspector protocol. (Ali Ijaz Sheikh) [#6792](nodejs/node#6792)
  - **Note: This feature is _experimental_, and it could be altered or removed.**
  - You can try this feature by running Node.js with the `--inspect` flag.
