I've added a check that skips those entries. I don't think that an UNKNOWN_DANE_INFO verify flag is needed. Having it may cause similar failures at the application layer, and wouldn't provide any significant information that the application can act on.

Both verify_ca() and verify_ee() abort DANE processing with DANE_E_UNKNOWN_DANE_DATA for unrecognised types. The correct response is to ignore that TLSA record.

If a new TLSA type is introduced then DANE checking will return an error and be ignored by clients. Instead, the clients may have been able to verify the certificate with another TLSA record or they should have rejected it when there are no more recognised records.

These functions should return 0 and set *verify |= DANE_VERIFY_UNKNOWN_DANE_INFO.
