 // Native side of java-class of same name.
 // Provides the ownership of and access to browser components required for
 // WebView functionality; analogous to chrome's TabContents, but with a
 // level of indirection provided by the AwContentsContainer abstraction.
 //
 // Object lifetime:
 // For most purposes the java and native objects can be considered to have
 // 1:1 lifetime and relationship. The exception is the java instance that
 // hosts a popup will be rebound to a second native instance (carrying the
 // popup content) and discard the 'default' native instance it made on
 // construction. A native instance is only bound to at most one Java peer over
 // its entire lifetime - see Init() and SetPendingWebContentsForPopup() for the
 // construction points, and SetJavaPeers() where these paths join.
