Introduce a priv field to 'struct format_field' for futher expansion.
(In https://lkml.org/lkml/2015/1/21/383 , Jiri Olsa gives a suggestion about changing lib traceevent to solve a bug of perf-convert-to-ctf, which is related to duplicated field names. I think his suggestion should be something like this patch. )
