a) All tests green under -race for both PILOSA_TXSRC=roaring and PILOSA_TXSRC=badger. b) Distinct is merged back into mainline pilosa. Seebs notes on the Distinct work: merge Distinct plugin back into main source tree, convert to Tx We drop all references to the Preemptively Deprecated Don't You Dare Use This extension interface, and move the one and only extension we had (Distinct) into the main executor. Also this fixes an arguable bug, which is that Container.AsBitmap() would panic on a nil parameter, but it should have returned an empty bitmap, because a nil *Ccontainer is a valid empty container. This simplifies logic significantly in Distinct. Fixes #569 #570 #571 #572 #573 #584 #585
