Sync / Firefox Accounts

Kit, Thom, and Mark putting the finishing touches on the new bookmarks engine. ✨ There’s a draft of a blog post that you can review!

Ed is putting the finishing touches on FxA Messages (formerly Pushbox 🖐📦), a service for delivering large push payloads to Firefox. This will be used for New Send Tab.

Thom is reworking how Sync backfills history records, reworked the bookmarks engine to transparently switch between the new and old engines after flipping the `services.sync.engine.bookmarks.buffer` pref, dug into profiling the new engine, and fixed more tests. 🐞

Mark optimized observer notifications in history sync. 👀
