* Reduce runtime prototype traversal for hasOwnProperty ([enisdenjo#52](https://github.com/ilijaNL/graphql-ws/issues/52)) ([1bb9218](1bb9218))

### Reverts

* Revert "refactor: emit client connect in next tick during testing" ([c10d0bf](c10d0bf))

### BREAKING CHANGES

* Because of the Protocol's strictness, an instant connection termination will happen whenever an invalid message is identified; meaning, all previous implementations will fail when receiving the new subprotocol ping/pong messages.

**Beware,** the client will NOT ping the server by default. Please make sure to upgrade your stack in order to support the new ping/pong message types.

A simple recipe showcasing a client that times out if no pong is received and measures latency, looks like this:
```js
import { createClient } from 'graphql-ws';

let activeSocket,
  timedOut,
  pingSentAt = 0,
  latency = 0;
createClient({
  url: 'ws://i.time.out:4000/and-measure/latency',
  keepAlive: 10_000, // ping server every 10 seconds
  on: {
    connected: (socket) => (activeSocket = socket),
    ping: (received) => {
      if (!received /* sent */) {
        pingSentAt = Date.now();
        timedOut = setTimeout(() => {
          if (activeSocket.readyState === WebSocket.OPEN)
            activeSocket.close(4408, 'Request Timeout');
        }, 5_000); // wait 5 seconds for the pong and then close the connection
      }
    },
    pong: (received) => {
      if (received) {
        latency = Date.now() - pingSentAt;
        clearTimeout(timedOut); // pong is received, clear connection close timeout
      }
    },
  },
});
```
* **uWebSockets:** The deprecated uWebSockets `request` context extra field has been dropped because it is stack allocated and cannot be used ouside the internal `upgrade` callback.
* **client:** Client `keepAlive` option has been renamed to `lazyCloseTimeout` in order to eliminate ambiguity with the client to server pings keep-alive option.
* **server:** The return function of `server.opened` (`closed`) now requires the close event code and reason for reporting to the `onDisconnect` callback.
* **server:** The `Context.subscriptions` record value can be either an `AsyncIterator` or a `Promise`.
* **client:** Client `retryTimeout` option has been replaced with the new `retryWait`.

`retryWait` allows you to control the retry timeout strategy by resolving the returned promise when ready. The default implements the randomised exponential backoff like so:
```ts
// this is the default
const retryWait = async function randomisedExponentialBackoff(retries: number) {
  let retryDelay = 1000; // start with 1s delay
  for (let i = 0; i < retries; i++) {
    retryDelay *= 2; // square `retries` times
  }
  await new Promise((resolve) =>
    setTimeout(
      // resolve pending promise with added random timeout from 300ms to 3s
      resolve,
      retryDelay + Math.floor(Math.random() * (3000 - 300) + 300),
    ),
  );
};
```
* **server:** You now "make" a ready-to-use server that can be used with _any_ WebSocket implementation!

Summary of breaking changes:
- No more `keepAlive`. The user should provide its own keep-alive implementation. _(I highly recommend [WebSocket Ping and Pongs](https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API/Writing_WebSocket_servers#Pings_and_Pongs_The_Heartbeat_of_WebSockets))_
- No more HTTP `request` in the server context.
- No more WebSocket in the server context (you're the one that creates it).
- You use your own WebSocket server
- Server exports only `makeServer` _(no more `createServer`)_

### Benefits
- You're responsible for the server (_any_ optimisation or adjustment can be applied)
- Any WebSocket server can be used (or even mocked if necessary)
- You control the disposal of the server (close or transfer clients however you wish)
- New `extra` field in the `Context` for storing custom values useful for callbacks
- Full control of authentication flow
- Full control over error handling
- True zero-dependency

### Migrating from v1

**Only the server has to be migrated.** Since this release allows you to use your favourite WebSocket library (or your own implementation), using [ws](https://github.com/websockets/ws) is just one way of using `graphql-ws`. This is how to use the implementation shipped with the lib:

```ts
/**
 * ❌ instead of the lib creating a WebSocket server internally with the provided arguments
 */
import https from 'https';
import { createServer } from 'graphql-ws';

const server = https.createServer(...);

createServer(
  {
    onConnect(ctx) {
      // were previously directly on the context
      ctx.request as IncomingRequest
      ctx.socket as WebSocket
    },
    ...rest,
  },
  {
    server,
    path: '/graphql',
  },
);

/**
 * ✅ you have to supply the server yourself
 */
import https from 'https';
import ws from 'ws'; // yarn add ws
import { useServer } from 'graphql-ws/lib/use/ws'; // notice the import path

const server = https.createServer(...);
const wsServer = new ws.Server({
  server,
  path: '/graphql',
});

useServer(
  {
    onConnect(ctx) {
      // are now in the `extra` field
      ctx.extra.request as IncomingRequest
      ctx.extra.socket as WebSocket
    },
    ...rest,
  },
  wsServer,
  // optional keepAlive with ping pongs (defaults to 12 seconds)
);
```
* This lib is no longer compatible with [`subscriptions-transport-ws`](https://github.com/apollographql/subscriptions-transport-ws). It follows a redesigned transport protocol aiming to improve security, stability and reduce ambiguity.
