[PATCH bpf-next 0/1] selftests/bpf: support custom per-test flags and multiple expected messages

[Eduard Zingerman <eddyz87@gmail.com>]

This patch allows to specify program flags and multiple verifier log
messages for the test_loader kind of tests. For example:

  tools/testing/selftets/bpf/progs/foobar.c:
  
    SEC("tc")
    __success __log_level(7)
    __msg("first message")
    __msg("next message")
    __flag(BPF_F_ANY_ALIGNMENT)
    int buz(struct __sk_buff *skb)
    { ... }

It was developed by Andrii Nakryiko ([1]), I reused it in a
"test_verifier tests migration to inline assembly" patch series ([2]),
but the series is currently stuck on my side.
Andrii asked to spin this particular patch separately ([3]).
