perf/core improvements and fixes:
- Accept a zero --itrace period, meaning "as often as possible". In the case
of Intel PT that is the same as a period of 1 and a unit of 'instructions'
(i.e. --itrace=i1i). (Adrian Hunter)
- Harmonise itrace's synthesized callchains with the existing --max-stack
tool option (Adrian Hunter)
- Allow time to be displayed in nanoseconds in 'perf script' (Adrian Hunter)
- Fix potential loop forever when handling Intel PT timestamps (Adrian Hunter)
- Slighly improve Intel PT debug logging (Adrian Hunter)
- Warn when AUX data has been lost, just like when processing PERF_RECORD_LOST
(Adrian Hunter)
- Further document export-to-postgresql.py script (Adrian Hunter)
- Add option to synthesize branch stack from auxtrace data (Adrian Hunter)
- Use equivalent logic to avoid using dso->kernel (Arnaldo Carvalho de Melo)
- Show proper error messages when parsing bad terms for hw/sw events (He Kuang)
- Tracepoint event parsing improvements (He Kuang)
- Store tracing mountpoint for better error message (Jiri Olsa)
- Add fixdep to tools/build, bringing it closer to the kernel counterpart, from
where it is being lifted (Jiri Olsa)
