boringssl/fuzz/ssl_ctx_api.cc
David Benjamin 6da9eaeef1 Bound expensive opcodes in ssl_ctx_api. 
The fuzzers are timing out on inputs that spam SSL_CTX_add1_chain_cert
and SSL_CTX_get0_chain_certs. In our current X509* caching
implementation, this can be quadratic. As this is an API fuzzer, not an
actual attack surface, this is not of much interest in itself, but
bounding this will let the fuzzers fuzz faster.
