7c2477d87a Fix the core/load-duplicates.bro test
The load-duplicates.bro test would never fail because loading
the provided script code twice wouldn't trigger an error.
Fixed this by changing the sample script content.  Also added a
test case to verify that an error occurs as expected
when two scripts with the same content are loaded.

7c48aad582 Update DTLS error handling
DTLS now only outputs protocol violations once it saw something that
looked like a DTLS connection (at least a client hello). Before the
danger that it misinterprets something is too high.

It has a configurable number of invalid packets that it can skip over
(because other protocols might be interleaved with the connection) and a
maximum amount of Protocol violations that it outputs because of wrong
packet versions.

995368e68c Remove variable content from weird names
This changes many weird names to move non-static content from the
weird name into the "addl" field to help ensure the total number of
weird names is reasonably bounded.  Note the net_weird and flow_weird
events do not have an "addl" parameter, so information may no longer
be available in those cases -- to make it available again we'd need
to either (1) define new events that contain such a parameter, or
(2) change net_weird/flow_weird event signature (which is a breaking
change for user-code at the moment).

Also, the generic handling of binpac exceptions for analyzers which
to not otherwise catch and handle them has been changed from a Weird
to a ProtocolViolation.

Finally, a new "file_weird" event has been added for reporting
weirdness found during file analysis.
