Summary:
If the surface passed in the transient request is to the surface of the
shell surface, KWin aborts. It's an obvious invalid request, so handle
it properly by sending an error.

Summary:
So far ConnectionThread dispatched events without checking for (protocol)
errors. But Wayland errors are considered fatal. We do need to consider
them.
This change introduces a way to detect errors and expose them in
ConnectionThread. Errors are handled gracefully, they are exposed, but
not considered application fatal. E.g. a new ConnectionThread could be
created afterwards.
This allows to add tests to verify error conditions.
