From: Mykyta Yatsenko <yatsenko@xxxxxxxx> Introduce a new libbpf API function bpf_object__prepare enabling more granular control over the process of bpf_object loading. bpf_object__prepare runs the same steps that bpf_object__load is running, before the actual loading of BPF programs. This API could be useful when we need access to initialized fields of bpf_object before program loading, for example: currently we can't pass bpf_token into bpf_program__set_attach_target, because token initialization is done during loading.
