Changes
Add new Rust XPCOM components
* WebRender: {{bug|webrender}} (shipped in Firefox 67, enabled for users with appropriate hardware)
** '''Why Rust?''' Code taken from Servo, has high performance; Rust's memory and thread safety provides protection against complexity.
* kvstore (key-value storage backed by LMDB): {{bug|1490496}} (shipped in Firefox 67)
** '''Why Rust?''' The rkv crate provides a safe, ergonomic wrapper around LMDB, our choice for simple key-value storage in Firefox. kvstore wraps rkv in an asynchronous XPCOM API for JS and C++ callers.
* XUL store, backed by rkv: {{bug|1460811}} (landed in Firefox 68, used in Nightly only)
* TLS certificate store, backed by rkv: {{bug|1429796}} (shipped in Firefox 68)
* Synced bookmark merger: {{bug|1482608}} (shipped in Firefox 68, on by default in Nightly and early Beta)
** '''Why Rust?''' Code sharing! The bookmark merging algorithm was factored out into a [https://crates.io/crates/dogear separate crate], and is shared between Desktop and [https://github.com/mozilla/application-services all our mobile products].
