perf/core improvements and fixes:

Browse source 
User visible:
 
 - 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)
 
 Developer stuff:
 
 - 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)
