Feature parity with libbpf 1.0

One of the major milestones for libbpf-rs is to reach feature-parity with libbpf-1.0 so that any bpf userspace program writable in C may be writable in Rust.
There are some APIs that are still missing. This is a compiled list of what is still needed and will be kept up-to-date as we go along. We greatly welcome and appreciate any contributions towards this milestone.
