> (2) Make a conferencing application with built-in text messaging (speech to text would be fun with this... probably should write that too)
> (3) WebRTC! SIP stacks in the browser can send MESSAGE requests. Why limit yourself to just making calls when you can send arbitrary messages to a communications application? (Note: if you can't mention WebRTC in a release, you're not trying very hard)
> 
> The above was made possible due to some rather major changes in the message core. This includes (but is not limited to):
> - Users of the message API can now register message handlers. A handler has two callbacks: one to determine if the handler has a destination for the message, and another to handle it.
> - All dialplan functionality of handling a message was moved into a message handler provided by the message API.
> - Messages can now have the technology/endpoint associated with them. Various other properties are also now more easily accessible.
> - A number of ao2 containers that weren't really needed were replaced with vectors. Iteration over ao2_containers is expensive and pointless when the lifetime of things is well defined and the number of things is very small.
> 
> res_stasis now has a new file that makes up its structure, messaging. The messaging functionality implements a message handler, and passes received messages that match an interested endpoint over to the app for processing.
> 
> Note that inadvertently while testing this, I reproduced ASTERISK-23969. res_pjsip_messaging was incorrectly parsing out the 'to' field, such that arbitrary SIP URIs mangled the endpoint lookup. This patch includes the fix for that as well.
