Add dedicated StreamBucket class

I think this is not right way. You are trying to use StreamBucket for two distinct things. I think the primary work here should be to get rid of resource bucket object. This is visible to users only through the bucket property. I would imaging we should rather call it StreamBucketHandle and it should be opaque. Another thing is replacing the actual object returned by changed function which is currently just stdClass. It would make sense to eventually change it to typed class that could be called StreamBucket but that's really something different and those two things should not be combined together IMO

Sorry I somehow thought that it's supposed to replace the stream bucket resource which is not the case here.

As you're really only interested in the class, perhaps use:

echo get_class($bucket), "\n";

Then you don't have to update the test later when bucket becomes an object, or datalen becomes dataLength.

It would be good idea if there were other tests which ensured the structure of StreamBucket. But I'd prefer to keep this test as-is in this case, since that's the only place where the properties are displayed.

It looks good to me.
