[PATCH 09/15] perf evsel: Move fprintf methods to separate source file

From: Arnaldo Carvalho de Melo
Date: Fri Apr 15 2016 - 17:51:52 EST


From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

They still use functions that would drag more stuff to the python
binding, where these fprintf methods are not used, so separate it.
