Add some easy move constructors
These are easy, since they can be inline. Most types that would
benefit from move constructors can't have inline move constructors
because these types use smart pointers whose destructor is invoked
in the type's move constructor. Implementing move constructors
out-of-line would break binary compatibility between C++98 and C++11
builds of Qt and its users, so that is not attempted here.
