[PATCH 07/37] perf tools: Do not use __perf_session__process_events() directly

[Namhyung Kim]

It's only used for perf record to process build-id because its file
size it's not fixed at this time due to remaining header features.
However data offset and size is available so that we can use the
perf_session__process_events() once we set the file size as the
current offset like for now.

It turns out that we can staticize the function again as it's the only
user and add multi file support in a single place.
