[PATCH 32/37] perf evsel: Adopt fprintf routine from 'perf evlist'

From: Arnaldo Carvalho de Melo
Date: Tue Dec 11 2012 - 17:56:04 EST


From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

So that we can print all the details when debugging other tools,
when we have just evlists and evsels, not a perf.data file.
