This patch adds a new require, `puppeteer/Errors`, that holds all the Puppeteer-specific error classes. Currently, the only custom error class we use is `TimeoutError`. We'll expand in future with `CrashError` and some others. Fixes #1694.
This roll includes: - https://crrev.com/568341 - DevTools: force-create execution contexts for mixed content iframes Fixes #2709.
We'll get more of these soon.
