This will ensure that we do not parse the data in chunks when passing it to the
LoadListener. Decoding in chunks can lead to incomplete sequences which will
lead to a failed decode.
Check for a cancelled LoadListener in StreamLoader and stop the load. This is
just a shortcut for downloaded or failed resources.
Cleanup some of the LoadListener code around resetting a few member variables.
Reset them in the status callback since that indicates a new response from the
server (or StreamLoader).
