This is split off from the unfinished patch I039d6f6. This only moves existing code around, makes use of chaining and such to make code more compact and hopefully more readable. Methods are renamed to reflect better what they actually do. No behavior should change. Change-Id: I3ba538c8c77ad4455bf0f0aa821ca14feadef7cc
