- No output by default yet.  Most of the activity is centered
   around generating the Unified2::alert event which ties together
   an IDSEvent and a packet.

  added a test case for dnp3 packets with only link layer
  added condition to check DNP3 packet without app layer data

1531980f3d Exec module and raw input reader fixes.
- Do stream mode for commands done by exec module, it seems important
  in some cases (e.g. ensure requested stdin is fully written).

- For cases where the raw input reader knows the child process has been
  reaped, set the childpid member to a sentinel value to indicate such
  so we don't later think we should kill it or wait on it anymore.

- More error checking on dup2/close calls.  Set sentinel values when
  closing ends of pipes to prevent double closing a fd.

- Signal flag not set when raw input reader's child exits as a result
  of a signal.  Left out a test for this -- might be portability issues
  (e.g. Ubuntu seems to do things different regarding the exit code and
  also is printing "Killed" to stderr where other platforms don't).

2ccc963e22 Small fix to deal with a bug in the SSL log delay mechanism.

   to work around this problem for the moment.

2a0790c231 Changing the Bloom filter hashing so that it's independent of
CompositeHash.

We do this by hashing values added to a BloomFilter another time more
with a stable hash seeded only by either the filter's name or the
global_hash_seed (or Bro's random() seed if neither is defined).

I'm also adding a new bif bloomfilter_internal_state() that returns a
string representation of a Bloom filter's current internal state. This
is solely for writing tests that check that the filters end up
consistent when seeded with the same value.

5fa9c5865b Factor out the need for a tag field in Files::AnalyzerArgs record.
This cleans up internals of how analyzer instances get identified by the
tag plus any args given to it and doesn't change script code a user
would write.
