Don't crash on broken GIF images

Broken GIF images could set invalid width and height
values inside the image, leading to Qt creating a null
QImage for it. In that case we need to abort decoding
the image and return an error.

Initial patch by Rich Moore.

Backport of Id82a4036f478bd6e49c402d6598f57e7e5bb5e1e from Qt 5

Fix logic for figuring out what ConfigureNotify positions can be trusted

When reading ahead in the queue for ConfigureNotify events, it's necessary
to look for intermediate ReparentNotify events as well, since they will
determine whether the position in the event can be trusted or not.
