3550a2b2d3 Update documentation for DNS "Z" field
According to RFC 2535, RFC 3655, and RFC 4035, the Z field has been
partitioned into three 1-bit fields.  Therefore, we cannot claim in
the documentation that it always has the value zero.

6d836b7956 More stats improvements
Broke out the stats collection into a bunch of new Bifs
in stats.bif.  Scripts that use stats collection functions
have also been updated.  More work to do.

2b0a28686a Cleaned up stats collection.
- Removed the gap_report event.  It wasn't used anymore
   and functionally no more capable that scheduling events
   and using the get_gap_summary bif.

 - Added functionality to Dictionaries to count cumulative
   numbers of inserts performed.  This is further used to
   measure the total number of connections of various types.
   Previously only the number of active connections was
   available.

 - The Reassembler base class now tracks active reassembly
   size for all subclasses (File/TCP/Frag & unknown).

 - Improvements to the stats.log.  Mostly, more information.

mscrl.microsoft.com is the proper hostname, however to be safe, let's use regex to identify it.

- Daniel Guerra pointed out a type issue for SIP
   request and response code length fields which is now
   corrected.
 - Some redundant code was removed.
 - if/else tree modified to use switch instead.

28f4d45d33 Fix potential race condition when logging VLAN info to conn.log
Lowered priority of a connection_state_remove event handler to ensure
that the "conn" field is initialized in the connection record before
attempting to add the VLAN tags.

401e6c9102 Extend ssl dpd signature to allow alert before server_hello.
The alert in this case is caused by the server name in the SNI not being
recognized by the server, which triggers an alert. Since the server is
an apache, and this might happen reasonably often, the new signature
allows one TLS alert before the server hello is expected.

horizontal scroll bars, and removed some redundant sections that were
just outdated copies of information in the auto-generated reference

36b5a4db08 Merge branch 'master' of https://github.com/knielander/bro
I reworked this a bit:

    - Moved the globals into a new Pcap::* namespace, and renamed them
      slightly.

    - Moved the definitions of the globals into pcap/const.bif.

    - Also moved the existing 'snaplen' into Pcap::* and removed
      SnapLen() from the PktSrc API (it's really a pcap thing).

    - Likewise moved the existing functions precompile_pcap_filter,
      install_pcap_filter, and pcap_error, into Pcap::*.

    - Did some more refactoring for the pcap code.

* 'master' of https://github.com/knielander/bro:
  Refactored patch (removed options, less ambiguous name)
  Allow Bro to run in fanout mode.
  Allow libpcap buffer size to be set manually.

  Update calls of Base64 functions.
  Refactoring of Base64 functions.

I've removed the additional bif for encoding with a connection, as I'm
not sure there's much of a use case for it; we can always add it back
later if it turns out there is. I've also renamed
decode_base64_intern() to decode_base64_conn() to be a bit more
explicit about the difference.

9cd4071cb3 Add Q and update I documentation for conn history
- Q (MULTI_FLAG_PKT) was not in the documentation for the history field.

- I (FIN_RST_PKT) was documented incorrectly. It was documented as a
SYN+RST, when it actually represents a FIN+RST.

The new documentation was derived from:
d3f513f/src/analyzer/protocol/tcp/TCP.cc (L493)

ac5c4f117f Removing the yielding_teredo_decapsulation option.
With the more precise Teredo option, it seems no longer needed, and it
was a bit of a fragile mechanism to begin with.

a9867c706d Make Teredo DPD signature more precise.
Contributed by Martina Balint in https://github.com/bro/bro/pull/39.

(I didn't merge the github branch, as that has some more stuff in its
history. Instead I applied the single-line change directly.)
