Subject: [PATCH] Check if codec still exists before handling tunneling events

The tunneling callbacks are sent via Handler messages and may be
handled after the codec/surface was changed or released.

We already guard against the codec/surface change condition by
creating a new listener and verifying that the current callback
happens for the correct listener instance, but we don't guard
against a released codec yet.
