Add program extension tests that build on top of fexit_bpf2bpf tests. Replace three global functions in previously loaded test_pkt_access.c program with three new implementations: int get_skb_len(struct __sk_buff *skb); int get_constant(long val); int get_skb_ifindex(int val, struct __sk_buff *skb, int var); New function return the same results as original only if arguments match. new_get_skb_ifindex() demonstrates that 'skb' argument doesn't have to be first and only argument of BPF program. All normal skb based accesses are available.
