Sorry, we cannot get this patch in 19.08-rc1 because
it is accessing the memory configuration which is now internal:

    if (!mcfg->single_file_segments) {
        MIF_LOG(ERR, "Zero-copy doesn't support multi-file segments.");
        return -ENOTSUP;
    }

We need to find another way of doing this check,
or think about avoiding such limitation.

Sorry for the inconvenience.

PS: While at it, I advise to split your patch.
You are moving some functions in a new file and do some changes in the
same patch, so it is very hard to understand what are the real changes.
