2002fd7f90 Merge remote-tracking branch 'origin/topic/johanna/ssl-resumption'
* origin/topic/johanna/ssl-resumption:
  Update baseline of new SSL policy script for changes
  update test baselines
  Mark everything below 2048 bit as a weak key (Browsers will stop accepting 1024 bits soon, so we can be of that opinion too).
  add information about server chosen protocol to ssl.log, if provided by alpn.
  change SSL log to contain a boolean flag signaling if a session was resumed instead of the (usually not really that useful) session ID the client sent.

9301ef5a4f Fixing SMTP state tracking.
This fixes the case that an SMTP session has multiple mails sent from
the originator but we miss the server's response (e.g., because we
don't see server side packets at all).

67c0cc118d Add two more ssl events - one triggered for each handshake message and one
triggered for the tls change cipherspec message.

Also - fix small bug. In case SSL::disable_analyzer_after_detection was set
to F, the ssl_established event would fire after each data packet after the
session is established.

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.

de0ce6deed BIT-1156: Fix parsing of DNS TXT RRs w/ multiple character-strings.
The "dns_TXT_reply" event now uses a "vector of strings" as the final
parameter instead of just a "string" in order to support DNS TXT
resource records that contain multiple character-strings.

The format in which the TXT answers are logged by default is now changed
to be a list of strings of the form `fmt("TXT %d %s", |str|, str)`, one
for each character-string in the RR and delimited by a space (' ')
character.

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)

4ae52d9e1c Support parsing of several TLS extensions.
At the moment, we have support for:
elliptic_curves: client supported elliptic curves
ec_point_formats: list of client supported EC point formats
application_layer_protocol_negotiation: list of supported application layer protocols (used for spdy/http2 negotiation)
server_name: server name sent by client. This was supported before, but... a bit brittle.
