Service workers

This is Chromium's implementation of service workers. See the Service Worker specification.

Directory structure

content/browser/service_worker: Browser process code, including stored registration data, the inception of starting a service worker, and controlling navigations. The browser process has host objects of most live renderer entities that deal with service workers, and the bulk of work is performed by these host objects.
content/renderer/service_worker: Renderer process code. This should move to third_party/blink per Onion Soup.
content/common/service_worker: Common process code.
third_party/blink/common/service_worker: Common process code. Contains the implementation of third_party/blink/public/common/service_worker.
third_party/blink/public/common/service_worker: Header files for common process code that can be used by both inside Blink and outside Blink.
third_party/blink/public/mojom/service_worker: Mojom files for common process code that can be used by both Blink and content.
third_party/blink/public/platform/modules/service_worker: Blink Public API header files. This should be removed per Onion Soup.
third_party/blink/public/web/modules/service_worker: More Blink Public API header files. This should be removed per Onion Soup.
third_party/blink/renderer/modules/service_worker: Renderer process code in Blink. This is the closest code to the web-exposed Service Worker API.
