5f334d88c2 perf stat: Pass through 'struct outstate'
Now most of the print functions take a pointer to the struct outstate.
We have one in the evlist__print_counters() and pass it through the
child functions.

f07952b179 perf stat: Basic support for iostat in perf
Add basic flow for a new iostat mode in perf. Mode is intended to
provide four I/O performance metrics per each PCIe root port: Inbound Read,
Inbound Write, Outbound Read, Outbound Write.

The actual code to compute the metrics and attribute it to
root port is in follow-on patches.
