Now that bpftool relies on libbpf to get a "standard" textual representation for program, map, link, and attach types, we can make it list all these types (plus BPF helpers) that it knows from compilation time. The first use case for this feature is to help with bash completion. It also provides a simple way for scripts to iterate over existing BPF types, using the canonical names known to libbpf. The first patch adds a new subcommand "bpftool feature list" to do this, and the second one updates the bash completion to drop the hardcoded lists of map types or cgroup attach types.
