perf tools: Reorganize event processing routines, lotsa dups killed

While implementing event__preprocess_sample, that will do all of
the symbol lookup in one convenient function, I noticed that
util/process_event.[ch] were not being used at all, then started
looking if there were other functions that could be shared
and...

All those functions really don't need to receive offset + head,
the only thing they did was common to all of them, so do it at
one place instead.

Stats about number of each type of event processed now is done
in a central place.
