Add the missing infra code in the perf python bindings for measuring and
reading the counter values for the given perf event. Demonstrate the
usage of this with counting.py - a python version of counting.c

v1 -> v2:
1. Use the existing iteration support for evlist
2. Drop the use of next method
3. Use existing helper functions for python example

Gautam Menghani (4):
  perf python: Add support for perf_counts_values to return counter data
  perf python: Add evsel read method
  perf python: Add evlist close support
  perf python: Add counting.py as example for counting perf events
