This changes libbpfgo to call bpf_program__attach_iter directly from go instead of doing this via a C wrapper. What this means is that we maintained opts creation in C, but the actual libbpf attach call is done in go. This creates two new functions in libbpfgo.h as helpers: - bpf_iter_attach_opts_new() - bpf_iter_attach_opts_free()

As questioned in #254 (comment). |

This changes libbpfgo to call bpf_object__open_mem directly from go instead of doing this via a C wrapper. What this means is that we maintained opts creation in C, but the actual libbpf object open call is done in go. This creates two new functions in libbpfgo.h as helpers: - bpf_object_open_opts_new() - bpf_object_open_opts_free() Context: aquasecurity#304 Additionally, this commit enforces the use of defer and resolves a potential CKconfigPath leak when len(args.KConfigFilePath) is > 2.
