boringssl/crypto/x509/x509_test.cc
Adam Langley 1902d818ac Tighten and test name-checking functions. 
This change follows up from e759a9cd with more extensive changes and
tests:

If a name checking function (like |X509_VERIFY_PARAM_set1_host|) fails,
it now poisons the |X509_VERIFY_PARAM| so that all verifications will
fail. This is because we have observed that some callers are not
checking the return value of these functions.

Using a length of zero for a hostname to mean |strlen| is now an error.
It also an error for email addresses and IP addresses now, and doesn't
end up trying to call |strlen| on a (binary) IP address.

Setting an email address with embedded NULs now fails. So does trying to
configure an empty hostname or email with (NULL, 0).

|X509_check_*| functions in BoringSSL don't accept zero lengths (unlike
OpenSSL). It's now tested that such calls always fail.
