Remove all whitespace options/configuration everywhere


Remove all whitespace options/configuration everywhere

Depends on D20181. Depends on D20182. Fixes T3498. Ref T13161. My claim, at least, is that D20181 can be tweaked to be good enough to throw away this "feature" completely.

I think this feature was sort of a mistake, where the ease of access to diff -bw shaped behavior a very long time ago and then the train just ran a long way down the tracks in the same direction.

Test Plan: Grepped for whitespace, deleted almost everything. Poked around the UI a bit. I'm expecting the whitespace changes to get some more iteration this week so I not being hugely pedantic about testing this stuff exhaustively.
