[PATCH 09/19] perf tools: Rename struct perf_data_file to perf_data

[Arnaldo Carvalho de Melo <acme@kernel.org>]

From: Jiri Olsa <jolsa@kernel.org>

Rename struct perf_data_file to perf_data, because we will add the
possibility to have multiple files under perf.data, so the 'perf_data'
name fits better.
