[PATCH bpf-next 0/3] Introduce bpf_object__prepare

[Mykyta Yatsenko <mykyta.yatsenko5@gmail.com>]

From: Mykyta Yatsenko <yatsenko@meta.com>

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.

Mykyta Yatsenko (3):
  libbpf: introduce more granular state for bpf_object
  libbpf: split bpf object load into prepare/load
  selftests/bpf: add tests for bpf_object__prepare
