dbaf2877e9 selftests/bpf: allow specifying helper for BPF_SK_LOOKUP
Make the BPF_SK_LOOKUP macro take a helper function, to ease
writing tests for new helpers.

fb47d1d931 bpf: Add skb->sk, bpf_sk_fullsock and bpf_tcp_sock tests to test_verifer
This patch tests accessing the skb->sk and the new helpers,
bpf_sk_fullsock and bpf_tcp_sock.

The errstr of some existing "reference tracking" tests is changed
with s/bpf_sock/sock/ and s/socket/sock/ where "sock" is from the
verifier's reg_type_str[].

cfff578ed5 selftests/bpf: mark verifier test that uses bpf_trace_printk as BPF_PROG_TYPE_TRACEPOINT
We don't have this helper if the kernel was compiled without
CONFIG_BPF_EVENTS. Setting prog_type to BPF_PROG_TYPE_TRACEPOINT
let's verifier correctly skip this test based on the missing
prog_type support in the kernel.

40f2fbd5a5 selftests: bpf: break up test_verifier
Break up the first 10 kLoC of test verifier test cases
out into smaller files.  Looks like git line counting
gets a little flismy above 16 bit integers, so we need
two commits to break up test_verifier.
