7344052b50 Changing what's escaped when printing.
With this patch the model is:

    - "print" cleans the data so that non-printable characters get
      escaped. This is not necessarily reversible.

    - to print in a reversible way, one can go through
      escape_string(); this escapes backslashes as well to make the
      decoding non-ambigious.

    - Logging always escapes similar to escape_string(), making it
      reversible.

Compared to master, we also change the escaping as follows:

    - We now only escape with "\xXX", no more "^X" or "\0". Exception:
      backslashes.

    - We escape backlashes as "\\".

    - There's no "alternative" output style anymore, i.e., fmt() '%A'
      qualifier is gone.

Baselines in testing/btest are updated, external tests not yet.

Addresses BIT-1333.

a55ce01ef3 API changes to file analysis mime type detection.
Removed "file_mime_type" and "file_mime_types" event, replacing them
with a new event called "file_metadata_inferred".  It has a record
argument of type "inferred_file_metadata", which contains the mime type
information that the earlier events used to supply.  The idea here is
that future extensions to the record with new metadata will be less
likely to break user code than the alternatives (adding new events or
new event parameters).

Addresses BIT-1368.

cbbe7b52dc Review/fix/change file reassembly functionality.
- Re-arrange how some fa_file fields (e.g. source, connection info, mime
  type) get updated/set for consistency.

- Add more robust mechanisms for flushing the reassembly buffer.
  The goal being to report all gaps and deliveries to file analyzers
  regardless of the state of the reassembly buffer at the time it has to
  be flushed.

7a46a70b77 BIT-1240: Fix MIME entity file data/gap ordering.
MIME entities buffered data and passed it along to protocol analyzers in
discrete amounts, but a gap is always passed along right away, so the
ordering of these "events" can cause incorrect file analysis.  The
change here is to never leave any MIME data buffered -- it should now be
passed along line by line as it is seen, but may still temporarily make
use of a buffer allocated by the analyzer as it works on decoding
content.

d5513a0757 Improve multipart HTTP/MIME entity file analysis.
Singular CR or LF characters in multipart body content are no longer
converted to a full CRLF (thus corrupting the file) and it also no
longer considers the CRLF before the multipart boundary as part of the
content.

Addresses BIT-1235.

9301ef5a4f Fixing SMTP state tracking.
This fixes the case that an SMTP session has multiple mails sent from
the originator but we miss the server's response (e.g., because we
don't see server side packets at all).

ed4cd9352a Merge remote-tracking branch 'origin/topic/bernhard/even-more-ssl-changes'
Good stuff! (but I admit I didn't look at the OpenSSL code too closely :)

* origin/topic/bernhard/even-more-ssl-changes:
  small test update & script fix
  update baselines & add ocsp leak check
  Add policy script adding ocsp validation to ssl.log
  Implement verification of OCSP replies.
  Add tls flag to smtp.log. Will be set if a connection switched to startls.
  add starttls support for pop3
  Add smtp starttls support
  Replace errors when parsing x509 certs with weirds (as requested by Seth).
  move tls content types from heartbleed to consts.bro. Seems better to put them there...
  Add new features from other branch to the heartbleed-detector (and clean them up).
  Let TLS analyzer fail better when no longer in sync with the data stream. The version field in each record-layer packet is now re-checked.

dadfcde70e Merge branch 'topic/robin/event-dumper'
Changes:

   - Changing semantics of the new_event() meta event: it's raised
     only for events that have a handler defined. There are too many
     checks in Bro that prevent events wo/ handler from being even
     prepared to raise to do that differently.

   - Adding test case.

* topic/robin/event-dumper:
  New script misc/dump-events.bro, along with core support, that dumps events Bro is raising in an easily readable form.
  Prettyfing Describe() for record types.
