/**
 * \brief       Decode .lzma Streams and LZMA_Alone files with autodetection
 *
 * Autodetects between the .lzma Stream and LZMA_Alone formats, and
 * calls lzma_stream_decoder_init() or lzma_alone_decoder_init() once
 * the type of the file has been detected.
 *
 * \param       strm        Pointer to propertily prepared lzma_stream
 * \param       header      Pointer to hold a pointer to Extra Records read
 *                          from the Header Metadata Block. Use NULL if
 *                          you don't care about Extra Records.
 * \param       footer      Same as header, but for Footer Metadata Block.
 *
 * \return      - LZMA_OK: Initialization was successful.
 *              - LZMA_MEM_ERROR: Cannot allocate memory.
