This seems to come back to hardcoding config* vs including it in every
single format description.

I prefer to have all perf_event_attr fields (of interest) hard-coded in
the parser so that we can omit them for all actual format descriptions.

These would be: period, config, config1, config2 and stephane's new
branch_sample_type, although that might want to get a shorter name.
