The patch in this code review presents an additional problem to getting res_corosync up and running again. Unless it internalizes a significant chunk of the old event system code, it will not be able to communicate with older versions of Asterisk. One suggestion has been to break compatibility and use JSON blobs to transmit state.

I think json blobs based on the info from the new system sounds like a reasonable approach.  Thanks for the info!

> This removes unused code, event types, IE pltypes, and event IE types where possible and makes several functions private that were once public. This includes a renumbering of the remaining event and IE types which breaks binary compatibility with previous versions. The last remaining consumers of the old event system (or parts thereof) are main/security_events.c, res/res_security_log.c, tests/test_cel.c, tests/test_event.c, main/cel.c, and the CEL backends.
