We now commit protocol.ts files during the roll.
New utils/roll_browser.js helps with that.
This makes our installation very shallow:
- build installer;
- download browsers.
This patch:
- removes `browserType.downloadBrowserIfNeeded()` method. The method
turned out to be ill-behaving and cannot not be used as we'd like to (see #1085)
- adds a `browserType.setExecutablePath` method to set a browser
exectuable.
With this patch, we take the following approach towards managing browser downloads:
- `playwright-core` doesn't download any browsers. In `playwright-core`, `playwright.chromium.executablePath()` returns `null` (same for firefox and webkit).
- clients of `playwright-core` (e.g. `playwright` and others) download browsers one way or another.
They can then configure `playwright` with executable paths and re-export the `playwright` object to their clients.
- `playwright`, `playwright-firefox`, `playwright-chromium` and `playwright-webkit` download
browsers. Once browsers are downloaded, their executable paths are saved to a `.downloaded-browsers.json` file. This file is read in `playwright/index.js` to configure browser executable paths and re-export the API.
- special case is `install-from-github.js` that also cleans up old browsers.
Currently it was leading to an error if I tried to build it with a root user on a Linux environment. So in the end the type generation was just skipped:
```
22:51:55.757 $ node install-from-github.js
22:51:55.813 Building playwright...

```
Maybe we should also exit the script with an error code if the protocol generation was not successful.
`protocol.d.ts` had to move to `protocol.ts` otherwise typescript refuses to include it in the out directory.
Removed the old d.ts generator. It will need to be rewritten anyway.
These new types include private stuff that they probably shouldn't, and are missing documentation. I'll follow up with a better d.ts generator later.
