Perf trace can augment system calls with a BPF program passed as an
event. The BPF code for this lives in examples. This patch fixes the
example code to not used deprecated/removed APIs in libbpf. As libbpf
has similar header files to tools/perf/include/bpf the code is
transitioned to use the more standard libbpf code and the perf BPF
header files removed.

Ian Rogers (7):
  perf trace: Raw augmented syscalls fix libbpf 1.0+ compatibility
  perf trace: Etcsnoop fix libbpf 1.0+ compatibility
  perf trace: Augmented syscalls fix libbpf 1.0+ compatibility
  perf trace: hello fix libbpf 1.0+ compatibility
  perf trace: empty fix libbpf 1.0+ compatibility
  perf trace: 5sec fix libbpf 1.0+ compatibility
  perf bpf: Remove now unused BPF headers
