John Firebaugh afead4e749 [core] Return {Source,Layer}::getID by value ...

Avoid dangling references in the following sequence:

    auto& id = layer->getID();
    layer->setMaxZoom(2);
    std::cout << id;

The reference would be dangling because mutating the layer allocates a new Immutable impl, and there may be no references to the prior impl, which held the id.
