New features:
- Dynamicly change verbosity level by pressing 'V' in the 'perf top/report'
hists TUI browser (Alexis Berlemont)
- Implement 'perf trace --delay' in the same fashion as in 'perf record --delay',
to skip sampling workload initialization events (Alexis Berlemont)

'perf list LONGEST_LAT' works just the same as 'perf list longest_lat' (Andi Kleen)
- Show instruction bytes and lenght in 'perf script' for Intel PT and BTS (Andi Kleen, Adrian Hunter)
E.g:
% perf record -e intel_pt// foo
% perf script --itrace=i0ns -F ip,insn,insnlen
