Be ready to lose a merge race on the confbridge changes.</pre>

While I can certainly see why you're doing it - checking each return and returning NULL and on the success path bumping it by one and returning the same pointer is a bit tedious - it feels like this could be abused. In general, people shouldn't be ref bumping something that is NULL.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I'm not sure it's ever reasonable to blindly invoke a virtual function on a NULL message. A message that failed allocation should never be published.</pre>

<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;">It's true that the message won't be published, but there are other use cases where you end up with a NULL message (such as with caching). It's easy enough to make the function NULL safe, so I'm sticking with it.</pre>

those messages for AMI and res_stasis events can be cumbersome.
This patch adds a vtable to stasis_message_type, with to_ami and
to_json virtual functions. These allow messages to be handled
abstractly without putting module-specific code in core.
As an example, the VarSet AMI event was refactored to use the to_ami
virtual function.
Additionally, I finally got tired of the boilerplate incrementing AO2
refcounts, so I added an ao2_ref1() macro, which is NULL safe and
returns the object.</pre>
