Andrii Nakryiko e0e3ea888c libbpf: Allow passing user log setting through bpf_object_open_opts ... Allow users to provide their own custom log_buf, log_size, and log_level at bpf_object level through bpf_object_open_opts. This log_buf will be used during BTF loading. Subsequent patch will use same log_buf during BPF program loading, unless overriden at per-bpf_program level. When such custom log_buf is provided, libbpf won't be attempting retrying loading of BTF to try to provide its own log buffer to capture kernel's error log output. User is responsible to provide big enough buffer, otherwise they run a risk of getting -ENOSPC error from the bpf() syscall. See also comments in bpf_object_open_opts regarding log_level and log_buf interactions.
