Fix OCSP Status Request extension unbounded memory growth
A malicious client can send an excessively large OCSP Status Request extension. If that client continually requests renegotiation, sending a large OCSP Status Request extension each time, then there will be unbounded memory growth on the server. This will eventually lead to a Denial Of Service attack through memory exhaustion. Servers with a default configuration are vulnerable even if they do not support OCSP. Builds using the "no-ocsp" build time option are not affected. I have also checked other extensions to see if they suffer from a similar problem but I could not find any other issues. CVE-2016-6304 Issue reported by Shi Lei. Reviewed-by: Rich Salz <email@example.com>
