9c6402bd91 More smb_files.log improvements.
- Actually get the path into the smb_files.log now.
 - When a share root is having the "create" message used on it,
   instead of giving a null file name, now give a special
   indicator of "<share_root>".
 - Update test baselines.

90559a3372 Disabled the attempt at support for the SMB2 SetInfo message.
It was causing reporter warnings and was so wildly incomplete
that it provided no benefit.

b9afc01d91 Fixed a problem with file names and path names containing nulls.
This would come up when a string is UTF-16 containing characters
outside of straight ASCII.  The file analysis framework uses
CheckString to create file IDs which can't cope with the NULL bytes.

d453dc149c A lot of changes to SMB analyzer.
- Add beginning of infrastructure for pipe support in SMB2.
 - Improve identification of non-file tree mappings.
 - Stop passing pipe data to the file analysis framework.
 - Reduce log volume in smb_files.log by watching for repeated
   files being seen so that you don't end up with nearly
   the exact same log line over and over and over.
 - Lots of little whitespace and indentation changes.

41e2eaa02d Source clean up and some fixes for SMB.

   elements are included.

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.

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.

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.)
