Changes between 0.9.7b and 0.9.7c [30 Sep 2003]
*) Fix various bugs revealed by running the NISCC test suite:
Stop out of bounds reads in the ASN1 code when presented with
invalid tags (CAN-2003-0543 and CAN-2003-0544).
Free up ASN1_TYPE correctly if ANY type is invalid (CAN-2003-0545).
If verify callback ignores invalid public key errors don't try to check
certificate signature with the NULL public key.

*) New -ignore_err option in ocsp application to stop the server
exiting on the first error in a request.

if the server requested one: as stated in TLS 1.0 and SSL 3.0
