    pstore: add lzo/lz4 compression support · 8cfc8ddc

    Like zlib compression in pstore, this patch added lzo and lz4
    compression support so that users can have more options and better
    compression ratio.
    
    The original code treats the compressed data together with the
    uncompressed ECC correction notice by using zlib decompress. The
    ECC correction notice is missing in the decompression process. The
    treatment also makes lzo and lz4 not working. So I treat them
    separately by using pstore_decompress() to treat the compressed
    data, and memcpy() to treat the uncompressed ECC correction notice.
