Saw a reply on the original pull request that the WebSocket using a random port broke their set up so I added a `--websocket` or `-w` argument similar to the `-p` argument to allow manually setting this port also. 

Fixes #4495

Here's my approach for replacing the XHR on-demand-entries pinger #1364 #4495. I'm not sure if this is the way everyone wants to accomplish this since I saw mention of using a separate server and port for the dynamic entries websocket, but thought this would be a fairly clean solution since it doesn't need that.

With this method the only change when using a custom server is you have to listen for the upgrade event and pass it to next.getRequestHandler(). Example: 
```
const server = app.listen(port)
const handleRequest = next.getRequestHandler()

if(dev) {
  server.on('upgrade', handleRequest)
}
```

Couldn't find a reference to these functions as next-server uses the renderToHTML directly.

It is native by webpack-dev-middleware 3.1.0 up

Change the ignore patterns to ignore `.git/` folder.
Add Windows pattern matching for `.next/` and `.git/` folders.

Fixes #5429

- Implements Lerna
- Moves all source code into `packages/next`
- Keeps integration tests in the root directory

First wave of changes. Just landing this first so that there is a base to build on.

@timneutkens 

This simple change seems to work for me:

```
const ignored = [
    '**/.*',
    'node_modules'
]
```

I believe the regex is used here to try and work on windows as well. So, I wasted a bunch of time trying to figure out how to use a regex and/or the `path` module to ignore the parent directories until I noticed the following:

> glob patterns are not filepaths. They are a type of regular language that is converted to a JavaScript regular expression. Thus, when forward slashes are defined in a glob pattern, the resulting regular expression will match windows or POSIX path separators just fine.

this is from the [anymatch](https://github.com/micromatch/anymatch) documentation which is what webpack uses accoring to this:

https://webpack.js.org/configuration/watch/#watchoptions-ignored

I've verified this glob pattern solves the problem in my environment, can someone test and verify that this works on windows?

Closes #4813

* Compile pages to .next/static/<buildid>/pages/<page>

* Fix test

* Use constant for static directory

* Add comment about what the middleware does

Webpack 4, react-error-overlay, react-loadable (major)

Fixes #4664

The prepares for next-server.

I also took this as an opportunity to get all build directory paths from a single location, as they were previously scattered across webpack/babel plugins and loaders.

When changing a page `/_app` can be seen as “updated”,  but the router shouldn’t reload it, because there is an ongoing/going to be ongoing update.
