perf sched latency: Fix thread pid reuse issue (2015-11-05 12:51:00 -0300)

perf/core improvements and fixes:

User visible:

- Fix 'perf top' segfault related to splitting overlapping mmaps (Jiri Olsa)

- Fix 'perf sched latency' when there is pid/tid reuse (Jiri Olsa)

- Fix documentation for 'perf trace -i' (Peter Feiner)


- Make the LINUX_VERSION_CODE define available for bpf scriptlets to use (Wang Nan)

- Pass the number of configured CPUs via the __NR_CPUS__ define to bpf scriptlets (Wang Nan)

- Fix libbpf compiler warning on CentOS 6 (Namhyung Kim)

- Only be verbose in several perf test entries, bpf included, when -v is used (Wang Nan)

- Don't run the 'build-test' entries always in the same order, the full
set takes a long time, so sometimes we interrupt, shuffling them avoids
running just the first same few in interrupted runs (Arnaldo Carvalho de Melo)

- Change FEATURE-DUMP to FEATURE-DUMP.libbpf in .gitignore and 'clean' make target (Yunlong Song)

- 'perf stat' refactorings to avoid duplicated code (Andi Kleen)
