perf evsel: Introduce perf_evlist
Killing two more perf wide global variables: nr_counters and evsel_list
as a list_head.
There are more operations that will need more fields in perf_evlist,
like the pollfd for polling all the fds in a list of evsel instances.
Use option->value to pass the evsel_list to parse_{events,filters}.
