Explictly null out our theora_state in theora_decode_init. The structure was already nulled in theora_encode_init, but not in decode,  which made theora_granule_time crash when it tried to access internal_encode  to determine whether the state is for an encoder or a decoder. Thanks to Nehal for the catch.
