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.
