Doug Thayer ebc62f01e4 Bug 1489588 - Disallow nsDisplayList copies and implement moves r=mattwoodrow 
Summary:
nsDisplayLists are currently a little bit error prone, since the
empty state of an nsDisplayList requires mTop == &mSentinel.
since &mSentinel will change when copied, while mTop won't,
this naturally creates an invalid state. Additionally, copies
don't quite make sense, since there is a requirement in the
destructor that destructed nsDisplayLists are empty - in which
case we would have to empty both the copied and the original
nsDisplayList - something which is unlikely to happen naturally.
Moves however are a natural operation - we just need to implement
the correct move behavior accounting for this mTop == &mSentinel
requirement.
