// NOT_INITIALIZED: represents the state that the Profile is not yet ready
// so that this service is not yet initialized, or Chrome is being shut
// down so that this is destroyed.
// STOPPED: ARC session is not running, or being terminated.
// CHECKING_REQUIREMENTS: Checking requirements before starting ARC.
// First, negotiates Google Play Store "Terms of Service" with a user. There
// are several ways for the negotiation, including opt-in flow, which shows
// "Terms of Service" page on ARC support app, and OOBE flow, which shows
// "Terms of Service" page as a part of Chrome OOBE flow. If user does not
// accept the Terms of Service, disables Google Play Store, which triggers
// RequestDisable() and the state will be set to STOPPED, then.
// Second, checks Android management status. Note that the status is checked
// for each ARC session starting, but this is the state only for the first
// boot case (= opt-in case). The second time and later the management check
// is running in parallel with ARC session starting, and in such a case,
// State is ACTIVE, instead.
// REMOVING_DATA_DIR: When ARC is disabled, the data directory is removed.
// While removing is processed, ARC cannot be started. This is the state.
// CHECKING_DATA_MIGRATION_NECESSITY: When ARC /data migration is enabled but
// not started yet, we need to check whether the migration is necessary by
// inspecting the content of /data. ARC cannot be started while the check is
// being performed, which is indicated by this state.
// READY: ARC is ready to run, but not running yet. This state is skipped on
// the first boot case.
// ACTIVE: ARC is running.
// STOPPING: ARC is being shut down.
//
// State transition should be as follows:
//
// NOT_INITIALIZED -> STOPPED: when the primary Profile gets ready.
// ...(any)... -> NOT_INITIALIZED: when the Chrome is being shutdown.
// ...(any)... -> STOPPED: on error.
//
// In the first boot case:
// STOPPED -> CHECKING_REQUIREMENTS: On request to enable.
// CHECKING_REQUIREMENTS -> ACTIVE: when a user accepts "Terms Of Service"
// and the auth token is successfully fetched.
//
// In the second (or later) boot case:
// STOPPED -> READY: when arc.enabled preference is checked that it is true.
// Practically, this is when the primary Profile gets ready.
// READY -> ACTIVE: when activation is allowed.
//
// In the disabling case:
// CHECKING_REQUIREMENTS -> STOPPED
// READY -> STOPPED
// ACTIVE -> STOPPING -> (maybe REMOVING_DATA_DIR ->) STOPPED
// STOPPING: Eventually change the state to STOPPED. Do nothing
// immediately.
// REMOVING_DATA_DIR: Eventually state will become STOPPED. Do nothing
// immediately.
// CHECKING_DATA_MIGRATION_NECESSITY: Eventually state will become STOPPED.
