    I thought it would be nice to keep it inline for core use, as it's called
    pretty often from the overflow path.

    A solution is to have a perf_output_copy_inline() in internal.h
    and export it through perf_output_copy() in buffer.c

    I thought it did too, but it actually use perf_output_sample().
