Commit 19a22f87 authored by thek@adventure.(none)'s avatar thek@adventure.(none)

Bug#35997 Event scheduler seems to let the server crash, if it is embedded.

EVENT we give a warning, and do not create anyting. On ALTER EVENT
we give a error, and do not change the event.

created or altered to the ENABLED (default) state. If so, then we
give a warning, and change the state to DISABLED.
