- Added a field named $last_alert to the SSL log. This doesn't even
indicate the direction the alert was sent, but we need to start somewhere.
- The x509_certificate function has an is_orig field now instead of
is_server and it's position in the argument list has moved.
- A bit of reorganization and cleanup in the core analyzer.
- Certificate validation volume has been greatly cut down by
caching results.
- Cert hashing is now done in one place instead of being repeated
everywhere a cert hash was needed.
- Some small cleanups for notice suppression that should greatly reduce
duplicate notice volume about invalid certificates.
