perf bpf: Show more BPF program info in print_bpf_prog_info()
This patch enables showing bpf program name, address, and size in the
header.
Before the patch:
perf report --header-only
...
# bpf_prog_info of id 9
# bpf_prog_info of id 10
# bpf_prog_info of id 13
After the patch:
# bpf_prog_info 9: bpf_prog_7be49e3934a125ba addr 0xffffffffa0024947 size 229
# bpf_prog_info 10: bpf_prog_2a142ef67aaad174 addr 0xffffffffa007c94d size 229
# bpf_prog_info 13: bpf_prog_47368425825d7384_task__task_newt addr 0xffffffffa0251137 size 369
Committer notes:
Fix the fallback definition when HAVE_LIBBPF_SUPPORT is not defined,
i.e. add the missing 'static inline' and add the __maybe_unused to the
args. Also add stdio.h since we now use FILE * in bpf-event.h.
