Shai Erera resolved LUCENE-5425.
--------------------------------

       Resolution: Fixed
    Fix Version/s: 4.7
                   5.0

Committed to trunk and 4x. I renamed MutableDocIdSet to Docs as it wasn't a DocIdSet anymore.

> In FacetsCollector, creation of bits in MatchingDocs are allocated per query. For large indexes where maxDocs are large creating a bitset of maxDoc bits will be expensive and would great a lot of garbage.
> Attached patch is to allow for this allocation customizable while maintaining current behavior.
