Restructure perf list so that it uses callbacks to print events and
metrics. Use the callbacks to implement json output. In the process
add documentation to pmu.h, avoid some sorting of events, fix some
command line and output bugs.

  perf pmu: Add documentation
  tools lib api fs tracing_path: Add scandir alphasort
  perf tracepoint: Sort events in iterator

  perf pmu: Restructure print_pmu_events
  perf list: Reorganize to use callbacks
  perf list: Add json output option
