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.
