Ensure that low-level APIs behave uniformly across the libbpf as follows:
- in case of an error, errno is always set to the correct error code;
- when libbpf 1.0 mode is enabled with LIBBPF_STRICT_DIRECT_ERRS option to
libbpf_set_strict_mode(), return -Exxx error value directly, instead of -1;
- by default, until libbpf 1.0 is released, keep returning -1 directly.
More context, justification, and discussion can be found in "Libbpf: the road
to v1.0" document ([0]).
