<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Technically it should be using ast_atomic_fetchadd_int() to get a guaranteed consistent value but it isn't done anywhere else in Asterisk this way.</pre>

<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 patch fixes to situations that could cause the CEL LINKEDID_END event to be missed.
1) During a core stop gracefully, modules are unloaded when ast_active_channels == 0. The LINKDEDID_END event fires during the channel destructor. This means that occasionally, the cel_* module will be unloaded before the channel is destroyed. It seemed generally useful to wait until the refcount of all channel == 0 before unloading, so I added a channel counter and used it in the shutdown code.
2) During a masquerade, ast_channel_change_linkedid is called. It calls ast_cel_check_retire_linkedid which unrefs the linkedid in the linkedids container in cel.c. It didn't ref the new linkedid. Now it does. I also changed the logic a little, since it used to call ast_channel_linkedid_set() even when it hadn't changed (or was blank, which should be verboten).
(this patch is against trunk, but it will go in 1.8+)</pre>
