// ServiceWorkerInstalledScriptsSender serves the service worker's installed
// scripts from ServiceWorkerStorage to the renderer through Mojo data pipes.
// ServiceWorkerInstalledScriptsSender is owned by ServiceWorkerVersion. It is
// created for worker startup and lives as long as the worker is running.
//
// SWInstalledScriptsSender has three phases.
// 1. The sender sends all installed scripts to the renderer without any
//    requests from the renderer. This initial phase is called "streaming".
//    |state_| is kSendingScripts. When all installed scripts are sent, moves to
//    the phase 2.
// 2. The sender is idle. |state_| is kIdle. If the renderer calls
//    RequestInstalledScript, moves to the phase 3.
// 3. The sender sends requested scripts. |state_| is kSendingScripts. When all
//    the requested scripts are sent, returns to the phase 2.
