Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

User visible changes:

  - Fix a segfault in 'perf probe' when removing uprobe events. (Masami Hiramatsu)

  - Synthesize COMM event for workloads started from the command line in 'perf
    record' so that we can have the pid->comm mapping before we get the real
    PERF_RECORD_COMM switching from perf to the workload. (Namhyung Kim)

  - Fix build tools/vm/ due to removal of tools/lib/api/fs/debugfs.h.
    (Arnaldo Carvalho de Melo)

Infrastructure changes:

  - Fix the make tarball targets by including the recently added err.h header in
    the perf MANIFEST file. (Jiri Olsa)

  - Don't assume that the event parser returns a non empty evlist. (Wang Nan)

  - Add way to disambiguate feature detection state files, needed to use
    tools/build feature detection for multiple components in a single O= output
    dir, which will be the case with tools/perf/ and tools/lib/bpf/.
    (Arnaldo Carvalho de Melo)

  - Fixup FEATURE_{TESTS,DISPLAY} inversion in tools/lib/bpf/. (Arnaldo Carvalho de Melo)
