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.
