This set adds "struct_ops" support to bpftool.

The first two patches improve the btf_dumper in bpftool.
Patch 1: print the enum's name (if it is found) instead of the
         enum's value.
Patch 2: print a char[] as a string if all characters are printable.

"struct_ops" stores the prog_id in a func ptr.
Instead of printing a prog_id,
patch 3 adds an option to btf_dumper to allow a func ptr's value
to be printed with the full func_proto info and the prog_name.

Patch 4 implements the "struct_ops" bpftool command.

Hi Martin, I have a few very small nits on patch 4 -- please see related
message -- but other than this your series looks good to me.

Thanks,
