* Protocol used to relay chrome observer notifications related to clearing data
* to SessionStorageManager instances in content processes. A single instance is
* created by each content process when LocalStorage NextGen is enabled. When
* LSNG is disabled, the notifications are instead propagated via
* PBackgroundStorageChild. This does mean there are potentially slight ordering
* differences in when the notification will be received and processed. It's
* okay for this protocol to be managed by PContent rather than PBackground
* because these notifications are both rare and to-child-only. (Legacy
* LocalStorage was moved to PBackground from PContent because of parent-process
* main-thread contention for the processing of "parent:" messages in a very
* performance-sensitive context!)
