To support multi-prog link-based attachments for new netns attach types, we need to keep track of more than one bpf_link per attach type. Hence, convert net->bpf.links into a list, that currently can be either empty or have just one item. Instead of reusing bpf_prog_list from bpf-cgroup, we link together bpf_netns_link's themselves. This makes list management simpler as we don't have to allocate, initialize, and later release list elements. We can do this because multi-prog attachment will be available only for bpf_link, and we don't need to build a list of programs attached directly and indirectly via links. No functional changes intended.
