Add new api function: bpf_program__attach_netfilter. It takes a bpf program (netfilter type), and a pointer to a option struct that contains the desired attachment (protocol family, priority, hook location, ...). It returns a pointer to a 'bpf_link' structure or NULL on error. Next patch adds new netfilter_basic test that uses this function to attach a program to a few pf/hook/priority combinations. v2: change name and use bpf_link_create.
