08399da6cb Files transferred over FTP were showing incorrect sizes.
The server-reported file size was being collected poorly and if
a file name had a number in it, that was reported as the file
size instead of the actual size.

A new test is included to avoid reintroducing the problem.

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.

f89874b9e9 Merge branch 'patch-4' of https://github.com/aeppert/bro
* 'patch-4' of https://github.com/aeppert/bro:
  (BIT-1545) Add "disable_analyzer_after_detection" en lieu of "skip_processing_after_detection"

I also removed the old disable_analyzer_after_detection option
completely - if someone wants that, they can just catch the event
themselves and call skip_further_processing.

I also adjusted the ssh test case to contain conn.log to prevent
re-addition of this problem in the future.

c93b057a97 (BIT-1545) Add "disable_analyzer_after_detection" en lieu of "skip_processing_after_detection"
The default of "skip_processing_after_detection" is confusing and causes conn.log to not be written as one would assume, plus the counters are not incremented and thus some kinds of potential detections are short-changed. I propose adding "disable_analyzer_after_detection" which would react, on the surface, the same way by disabling the SSH analyzer, but allowing conn.log to be written appropriately.

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.

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.

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.

* 'topic/jgras/base64-logging' of https://github.com/J-Gras/bro:
  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)

574bcb0a51 Add simple XMPP StartTLS analyzer.
This is a very simple XMPP analyzer that basically only can parse the
protocol until the client and server start negotiating a TLS session. At
that point, the TLS analyzer is attached.

While the basic case seems to be working, I fully expect that I missed
something and that this might break in a lot of cases.
