ReqOptScorer, etc.

The most interesting scorer is DisjunctionScorer, and
I posted your code in bugzilla at bug 34193 to compare to that.
The other scorers already use skipTo on their subqueries for performance.

Some more remarks:

This could also be considered as a complete replacement of the rewritten
code because of the simplicity of the implementation.

There is a recent thread on constant scoring queries for which the
subscorers can used one by one.
