 // SyncSessionContext encapsulates the contextual information and engine
 // components specific to a SyncSession. A context is accessible via
 // a SyncSession so that session SyncerCommands and parts of the engine have
 // a convenient way to access other parts. In this way it can be thought of as
 // the surrounding environment for the SyncSession. The components of this
 // environment are either valid or not valid for the entire context lifetime,
 // or they are valid for explicitly scoped periods of time by using Scoped
 // installation utilities found below. This means that the context assumes no
 // ownership whatsoever of any object that was not created by the context
 // itself.
 //
 // It can only be used from the SyncerThread.
