ba3214cee5 Add some documentation for modbus data types.
This also removes a field named "len" from the ModbusHeaders
record type because it's not really necessary.

50cf694aae Moved link-layer addresses into endpoints.
The link-layer addresses are now part of the connection endpoints
following the originator-responder-pattern. The addresses are printed
with leading zeros. Additionally link-layer addresses are also extracted
for 802.11 plus RadioTap.

57aef6d49f Add MAC addresses to connection record.

A new script protocols/conn/mac-logging.bro adds these to conn.log
when loaded.

5b5589e167 Complete breakout of SMB, GSSAPI, and NTLM
- Looser coupling between these analyzers.
 - New ntlm.log (still pretty early)
 - Improved string handling for NTLM (convert UTF16 to UTF8)
 - SMB2 analyzer now supports GSSAPI.
 - Improved abstraction of DCE_RPC operations (still not finished)
 - Lots of whitespace cleanup.

562e5a9f63 Add bif that allows searching for all matching subnets in table.
Example:

global test: set[subnet] = {
	10.0.0.0/8,
	10.1.0.0/16,
	10.2.0.0/16,
	10.2.0.2/31
}

print matching_subnets(10.2.0.2/32, test);
->
[10.2.0.2/31, 10.2.0.0/16, 10.0.0.0/8]

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.

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.
  Allow Bro to run in fanout mode.
  Allowed libpcap buffer size to be set via configuration.

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.
