We build variants of kinit and test_acquire_cred that define their own symbols rk_dns_lookup, gethostbyname, gethostbyname2, and getaddrinfo to print a message and abort. For getaddrinfo, we abort only if the caller failed to specify AI_NUMERICHOST; otherwise we use dlsym(RTLD_NEXT, "getaddrinfo") instead. The new test tests/gss/check-nodns is like tests/gss/check-basic, but uses kinit_auditdns and test_acquire_cred_auditdns to verify that no DNS resolution happens. This test should work and be effective on ELF platforms where the getaddrinfo function is implemented by the symbol `getaddrinfo'. On non-ELF platforms it may not be effective -- and on platforms where the getaddrinfo function is implemented by another symbol (like `__getaddrinfo50') it may not work, but we can cross that bridge when we come to it. Verified manually that the test fails, with the expected error message and abort, without `block_dns = yes' in krb5-nodns.conf. No automatic test of the mechanism for now because it might not work on some platforms. XXX check-nodns.in is copypasta of check-basic.in, should factor out the common parts so they don't get out of sync.
