Subject: [PATCH 02/19] perf sort: Make column width code per hists instance
From: Arnaldo Carvalho de Melo <acme@...hat.com>
They were globals, and since we support multiple hists and sessions
at the same time, it doesn't make sense to calculate those values
considering all symbols in all sessions.
