/* X509_REQ_INFO is handled in an unusual way to get round

* invalid encodings. Some broken certificate requests don't

* encode the attributes field if it is empty. This is in

* violation of PKCS#10 but we need to tolerate it. We do

* this by making the attributes field OPTIONAL then using

* the callback to initialise it to an empty STACK.

* This means that the field will be correctly encoded unless

* we NULL out the field.

* As a result we no longer need the req_kludge field because

* the information is now contained in the attributes field:

* 1. If it is NULL then it's the invalid omission.

* 2. If it is empty it is the correct encoding.

* 3. If it is not empty then some attributes are present.
