New ASN1 macros which will encode an empty SEQUENCE OF.

Browse Source 
Fix CRL encoders to encode empty SEQUENCE OF.

The old code was breaking CRL signatures.

Note: it is best to add new macros because changing the
old ones could break other code which expects that behaviour.
None of this is needed with the new ASN1 code anyway...
