LUCENE-4404: add ListOfOutputs for FST to hold more than one output per input
> Add ListOfOutputs FST Outputs, replacing UpToTwoPositiveIntOutputs

> Key: LUCENE-4404
> URL: https://issues.apache.org/jira/browse/LUCENE-4404
> Project: Lucene - Core
> Issue Type: Improvement
> Reporter: Michael McCandless
> Assignee: Michael McCandless
> Fix For: 4.1, 5.0

> Spinoff from LUCENE-3842. This just generalizes the
> UpToTwoPositiveIntOutputs to a list of any arbitrary output, by
> wrapping any other Outputs impl. I also made separate methods to
> write/read a node-final output: since list of values can only occur on
> a final node output, this impl optimizes and avoids writing an extra
> byte per label for normal arc labels.
> This also fixes a bug in Builder that was sometimes failing to join
> multiple outputs together.
