    python scripts.

perf script:

  Song Liu:

  - Assume native_arch for pipe mode, fixing a segfault.

perf inject:

  Arnaldo Carvalho de Melo:

  - The tool->read() call may pass a NULL evsel, handle it.

core:

  Arnaldo Carvalho de Melo:

  - Move zalloc/zfree.c to tools/lib, further eroding tools/perf/util.[ch]

  - Use zfree() where applicable instead of open coded equivalent.

  - Add stdlib.h and some other headers to places where its needed and were
    getting via util.h, that doesn't need that anymore.

  - Use list_del_init() more thoroughly.

Miscellaneous:

  Leo Yan:

  - Fix use after free and potential NULL pointer derefs detected by the
    smatch tool in various places.

  Luke Mujica:

  - Remove a couple unused variables in the parse-events code.

  Numfor Mbiziwo-Tiapo:

  - Initialize variable to suppress memory sanitizer warning in the
