abhinavdangeti 7e36109b3c MB-28162: Provide API to estimate memory needed to run a search query 
This API (unexported) will estimate the amount of memory needed to execute
a search query over an index before the collector begins data collection.

Sample estimates for certain queries:
{Size: 10, BenchmarkUpsidedownSearchOverhead}
                                                           ESTIMATE    BENCHMEM
TermQuery                                                  4616        4796
MatchQuery                                                 5210        5405

Steve Yen c7a342bc7d scorch conjuncts match phrase test passes 
The conjunction searcher Advance() method now checks if its curr
doc-matches suffices before advancing them.

Steve Yen 620dcdb6f8 scorch uses prealloc'ed buffer for docNumberToBytes() 
On a couple of micro benchmarks on a dev macbook using bleve-query on
an index of 50K wikipedia docs, scorch is now faster than
upsidedown/moss on high-freq term search "text:date"...

       400 qps - upsidedown/moss
       404 qps - scorch before
       565 qps - scorch after
