Ondřej Surý e26aa4cbb1 Don't use reference counting in isc_timer unit ... The reference counting and isc_timer_attach()/isc_timer_detach() semantic are actually misleading because it cannot be used under normal conditions. The usual conditions under which is timer used uses the object where timer is used as argument to the "timer" itself. This means that when the caller is using `isc_timer_detach()` it needs the timer to stop and the isc_timer_detach() does that only if this would be the last reference. Unfortunately, this also means that if the timer is attached elsewhere and the timer is fired it will most likely be use-after-free, because the object used in the timer no longer exists. Remove the reference counting from the isc_timer unit, remove isc_timer_attach() function and rename isc_timer_detach() to isc_timer_destroy() to better reflect how the API needs to be used. The only caveat is that the already executed event must be destroyed before the isc_timer_destroy() is called because the timer is no longet attached to .ev_destroy_arg.
