We want to run MediaCacheStream::NotifyDataEnded() off the main thread. However, modifying mResourceID/mDidNotifyDataEnded/mNotifyDataEndedStatus in NotifyDataEnded() is getting in our way for they are main thread only members.

Thanks!

It is worth noting that when mDidNotifyDataEnded/mNotifyDataEndedStatus are modified off the main thread, the result of IsAvailableForSharing() becomes a changing value over time on the main thread. 2 consecutive IsAvailableForSharing() calls on the main thread might return different results.

Even though InitAsClone() is called only after IsAvailableForSharing() returns true, the assertion of MOZ_ASSERT(aOriginal->IsAvailableForSharing()) might still fail for the reason above.

So we need to remove checks for mDidNotifyDataEnded/mNotifyDataEndedStatus from IsAvailableForSharing().
