  DNSSEC support in Bro

I made several changes:

1a75ef2abd Remove "relay" family of Broker functions
Namely these are now removed:

    - Broker::relay
    - Broker::publish_and_relay
    - Cluster::relay_rr
    - Cluster::relay_hrw

The idea being that Broker may eventually implement the necessary
routing (plus load balancing) functionality.  For now, code that used
these should "manually" handle and re-publish events as needed.

620cd671ba Fix tracking of DCE-RPC context identifier mappings
This adds previously-missing support for "Alter Context"
request/response PDUs (initial patch contributed by Mark Fernandez).

Also, context ID arguments were added to dce_rpc_bind, dce_rpc_request,
and dce_rpc_response in order to properly track what endpoint/operation
a given opnum maps to.

35827eeb31 Add rate-limiting sampling mechanism for weird events
The generation of weird events, by default, are now rate-limited
according to these tunable options:

  - Weird::sampling_whitelist
  - Weird::sampling_threshold
  - Weird::sampling_rate
  - Weird::sampling_duration

The new get_reporter_stats() BIF also allows one to query the
total number of weirds generated (pre-sampling) which the new
policy/misc/weird-stats.bro script uses periodically to populate
a weird_stats.log.

There's also new reporter BIFs to allow generating weirds from the
script-layer such that they go through the same, internal
rate-limiting/sampling mechanisms:

  - Reporter::conn_weird
  - Reporter::flow_weird
  - Reporter::net_weird

Some of the code was adapted from previous work by Johanna Amann.

81133f3116 Merge remote-tracking branch 'origin/topic/seth/dhcp-update'
* origin/topic/seth/dhcp-update:
  Rework to the DHCP analyzer.
  First step of DHCP analyzer rearchitecture.
  Add .btest scripts for dhck_ack and dhcp_discover messages verifying that new options are correctly reported in dhcp.log records.
  Extend DHCP protocol analyzer with new options.

BIT-1924 #merged

Additional changes:

* Removed known-hosts.bro as the only thing populating its table was
  the already-removed known-hosts-and-devices.bro.  So a
  known_devices.log will no longer be generated.

* In dhcp-options.pac, the process_relay_agent_inf_option had a memleak
  and also process_auto_proxy_config_option looked like it accessed one
  byte past the end of the available bytestring, so fixed those.

Update consts.bro
Removed duplicated entries (`000001a0-0000-0000-c000-000000000046`, with `i=3, i=4`) and related comments line

This change should make this file more readable and it will be easier to convert it to other formats (personally I found it out while I was trying to convert this to a JavaScript structure).

be9f97d8b4 Updates to NTLM script handling.
- This separates NTLM handling away from SMB.
 - It logs more accurately when logins are succeed or fail
   or even if the resulting status of an authentication is
   unknown.
 - Adds some new fields where the server is indicating information
   about itself (server_nb_computer_name, server_dns_computer_name,
   and server_tree_name)

f39efd0317 Recognize TLS 1.3 negotiation correctly.
The way in which TLS 1.3 is negotiated was changed slightly in later
revisions of the standard. The final version is only sent in an
extension - while the version field in the server hello still shows TLS
1.2.

This patch makes ssl.log show the correct version again.
