Because a single Resource only has a single ResourceListener, injected Resources only gets wired up to the stream's ResourceAdaptationProcessor that was last to call SetResourceListener. This could potentially lead to the relevant stream not adapting based on the injected resource because it got wired up to the wrong stream's processor. This CL fixes this issue by introducing BroadcastResourceListener. By listening to 1 resource (the injected one), it can spawn N "adapter" resources that mirror's the injected resource's usage signal, allowing all ResourceAdaptationProcessor's to react to the signal. This is wired up in Call, and tests are updated to verify the signal gets through.
