* Use weak pointer to avoid race condition * Use DeleteSoon to delete pointer across threads * Simplify EventSubscriber * No need to manually mange V8 convertions * Fix cpplint warning We should update cpplint for this, but let's do it in other PR. * Move UI thread operations to EventSubscriber * Less and more assertions Some methods are now private so no more need to assert threads. * Fix cpplint warnings * No longer needs the EventEmitted * EventSubscriber => StreamSubscriber * Reduce the copies when passing data * Fix cpplint warnings
