Ting-Yu Lin 0be6d30488 Bug 1342994 Part 2 - Use UniquePtr to replace explicit new/delete and non-owing pointers in printing APIs. r=dholbert
Also, rewrite some for-loops as range-based.

Other APIs still using nsPrintObject* involve with
nsPrintData::mPrintDocList or nsPagePrintTimer::mPrintObj.

nsPrintEngine::FindPrintObjectByDOMWin() could have its argument converted
to UniquePtr, but it needs to return nullptr to represent "found nothing."
Therefore, I leave its argument as it was for consistency.
