<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This is the Asterisk v12 version of the https://reviewboard.asterisk.org/r/3127/ review.
The CEL data structures need to be protected during a configuration reload and shutdown. Asterisk crashed during a shutdown because CEL events were still in flight and the CEL data structures were already destroyed.
* Protected the cel_backends, cel_dialstatus_store, and cel_linkedids ao2 containers with a global ao2 object wrapper.
* Added NULL checks before use of the cel_backends, cel_dialstatus_store, and cel_linkedids ao2 containers in case the CEL module is already shutdown.
* Fixed overloading of the cel_linkedids held objects reference count. During shutdown any held objects would be leaked.
* Fixed memory leak of cel_linkedids held objects if the LINKEDID_END is not being tracked. The objects in the cel_linkedids container were not removed if the LINKEDID_END event is not used.
* Added access protection to the cel_backends container during the CLI "cel show status" command.
* Made cel_backends, cel_dialstatus_store, and cel_linkedids use the standard ao2 callback templates for the hash and cmp functions.
* Eliminated unnecessary uses of RAII_VAR().
* Made ast_cel_engine_init() cleanup alocated resources on failure.

* Checked CEL logs for APP_START/APP_END/LINKEDID_END events after a call.
* Shutdown asterisk with "core stop now" and "core stop gracefully" without any crashes.</pre>
