    lib: Prevent unaligned memory access and fix endianess in LZMA decode library.
    
    LZMA decode library used to retrieve output size by:
      outSize = *(UInt32 *)(src + LZMA_PROPERTIES_SIZE);
    
    'src' is aligned but LZMA_PROPERTIES_SIZE may refer to an unaligned address like
    src+5, and using that as integer pointer may fail on platforms like ARM. Also
    this will fail on systems using big-endian (outSize was encoded in
    little-endian).
    
    To fix this, reconstruct outSize in little-endian way.
