[PATCH 27/35] perf report: Rename 'perf_report' to 'report'

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

Reduce typing, functions use class__method convention, so unlikely to
clash with other libraries.

This actually was discussed in the "Link:" referenced message below.
