With `nodejs@15.0.1`, install puppeteer with `https_proxy` set causes an error like:
```
> puppeteer@5.4.1 install node_modules/puppeteer
> node install.js

This PR updates the socket transport code to swap between a Node web
socket transport or a web one based on the `isNode` environment. It also
adds unit tests to the browser tests that show we can connect in a
browser.
The `Puppeteer` class had two concerns:
* connect to an existing browser
* launch a new browser
The first of those concerns is needed in all environments, but the
second is only needed in Node.
https://github.com/puppeteer/puppeteer/pull/6484 landing enabled us to
pull the `Puppeteer` class apart into two:
1. `Puppeteer` which hosts the behaviour for connecting to existing
browsers.
2. `PuppeteerNode`, which extends `Puppeteer` and also adds the ability
to launch a new browser.
This is a non-breaking change, because Node users will still get an
instance of a class with all the methods they expect, but it'll be a
`PuppeteerNode` rather than `Puppeteer`. I don't expect this to cause
people any issues.
We also now have new files that are effectively the entry points for
Puppeteer:
* `node.ts`: the main entry point for Puppeteer on Node.
* `web.ts`: the main entry point for Puppeteer on the web.
* `node-puppeteer-core.ts`: for those using puppeteer-core (which only
exists in Node, not on the web).
Launching headless with a relative `userDataDir` hangs on Windows. Fix by calling `path.resolve` (idempotent) to add an absolute path instead in `defaultArgs`.
Issues: #3453
The `Launcher` class was serving two purposes:
1. Launch browsers
2. Connect to browsers
Number 1) only needs to be done in Node land, but 2) is agnostic; in a
browser version of Puppeteer we'll need the ability to connect over a
websocket to send commands back and forth.
As part of the agnostification work we needed to split the `Launcher` up
so that the connection part can be made agnostic. Additionally, I
removed dependencies on `https`, `http` and `URL` from Node, instead
leaning on fetch (via `node-fetch` if in Node land) and the browser
`URL` API (which was added to Node in Node 10).
By adding support for an environment variable `PUPPETEER_DOWNLOAD_PATH` it is possible to support downloading the browser binaries into a folder outside the `node_modules` folder. This makes it possible to preserve previously downloaded binaries in order to skip downloading them again.
* chore: enforce file extensions on imports
To make our output agnostic it should include file extensions in the
output, as per the ESM spec. It's a bit odd for Node packages but makes
it easier to publish a browser build.
* chore(docs): reduce warnings when generating docs
This is a bunch of small miscellaneous fixes that reduce the amount of
warnings logged when generating our new docs. The long term goal is to
get this list down to 0 warnings, but I'll do it in multiple PRs.
* satisfy doclint
This CL migrates all the tests to TypeScript. The main benefits of this is that we start consuming our TypeScript definitions and therefore find errors in them. The act of migrating found some bugs in our definitions and now we can be sure to avoid them going forwards.
You'll notice the addition of some `TODO`s in the code; I didn't want this CL to get any bigger than it already is but I intend to follow those up once this lands. It's mostly figuring out how to extend the `expect` types with our `toBeGolden` helpers and some other slight confusions with types that the tests exposed.

These files will be used by both the web and node versions of Puppeteer.
Another name for this might be "core" but I don't want to cause
confusion with the puppeteer-core package that we publish at the moment.
This is another step towards making Puppeteer agnostic of environment
and being able to run in Node or a browser.
The files in the `node` directory are ones that would only be needed in
the Node build - e.g. the code that downloads and launches a local
browser instance.
The long term vision here is to have three folders:
* node - Node only code
* web - Web only code
* common - code that is shared
But rather than do that in one PR I'm going to split it up to make it
easier to review and deal with.
