ed4cd9352a Merge remote-tracking branch 'origin/topic/bernhard/even-more-ssl-changes'
Good stuff! (but I admit I didn't look at the OpenSSL code too closely :)

* origin/topic/bernhard/even-more-ssl-changes:
  small test update & script fix
  update baselines & add ocsp leak check
  Add policy script adding ocsp validation to ssl.log
  Implement verification of OCSP replies.
  Add tls flag to smtp.log. Will be set if a connection switched to startls.
  add starttls support for pop3
  Add smtp starttls support
  Replace errors when parsing x509 certs with weirds (as requested by Seth).
  move tls content types from heartbleed to consts.bro. Seems better to put them there...
  Add new features from other branch to the heartbleed-detector (and clean them up).
  Let TLS analyzer fail better when no longer in sync with the data stream. The version field in each record-layer packet is now re-checked.

f0b244b8b0 Add new features from other branch to the heartbleed-detector (and clean them up).
We should now quite reliably detect scans/attacks, even when encrypted and not succesful.

eed94fab76 Merge remote-tracking branch 'origin/fastpath'
* origin/fastpath:
  Correct a notice for heartbleed. The notice is thrown correctly, just the message conteined wrong values.
  Improve/standardize some malloc/realloc return val checks.
  Improve file analysis manager shutdown/cleanup.

201fc7b25a Merge remote-tracking branch 'origin/topic/bernhard/ssl-analyzer'
* origin/topic/bernhard/ssl-analyzer:
  Fix a few failing tests
  Add very basic ocsp stapling support.
  Add documentation, consts and tests for the new events.
  Support parsing of several TLS extensions.
  Make SSL/TLS version detection less brittle.
  Nicer notices for heartbleed.
  rip out state handline from ssl analyzer.
  enable detection of encrypted heartbleeds.
  also extract payload data in ssl_heartbeat
  add to local.bro, add disclaimer
  make tls heartbeat messages a bit better.
  fix tabs.
  polish script and probably detect encrypted attacks too.
  detect and alert on simple case of heartbleed
  default to TLS when not being able to determine version
  add is_orig to heartbeat event
  Throw new event for heartbeat messages.

9b7eb293f1 Add documentation, consts and tests for the new events.
This also fixes the heartbleed detector to work for encrypted attacks in this
branch again. It stopped working, because the SSL analyzer now successfully detects
established connections, and the scripts usually disable analyzing after that.

(The heartbeat branch should not have been affected)

ef41cc7189 Nicer notices for heartbleed.
Duplicates are now excluded and the notice texts contain a bit more useful information.
