Allow passing a name for maps and programs and allow retrieving it via BPF_OBJ_GET_INFO_BY_FD. This requires a bunch of glue code because the bpf_prog_info, etc. structs are not compatible with Linux.

Internally both zero and EBPF_ID_NONE are used to refer to non-existing ID. Use zero when retrieving link info, since that aligns with Linux better.
