perf evsel: Subclassing
Provide a method to be called at tool start to config the perf_evsel
instance size, together with optional constructor and destructor.
This will be used so that perf_evsel doesn't always include a struct
hists, tools that works with hists/hist_entries, like report, top and
annotate, will, at start, tell the evsel class the size they need per
instance.
v2: Don't use exit as a name of a member of function parameter, as this
breaks the build on at least fedora14 and rhel6.
