This function will move all PADDING blocks to the end on the metadata, then merge them into a single block.
\note This function does not write to the FLAC file, it only modifies the chain.
\warning Any iterator on the current chain will become invalid after this call. You should delete the iterator and get a new one.
\param chain A pointer to an existing chain. \assert \code chain != NULL \endcode
