Jonathan Watt 41b151c8c4 Bug 1432651 p1 - Pass RemotePrintJobChild through to the places where it's needed. r=emilio
Given how nsIPrintSettings is passed around, stored and copied all over the
place, it's very hard to reason about where and when a RemotePrintJobChild is
needed or valid. This patch avoids all that by explicitly passing a
RemotePrintJobChild when it's needed.

Another reason to make this change is because RemotePrintJobChild really does
not belong on nsIPrintSettings. That interface is supposed to represent a
collection of settings for laying out the document that is to be printed.
