This patch adds a new message bus API to Asterisk.

This message bus provides a generic publish/subscribe mechanism within
Asterisk. This message bus is:

 - Loosely coupled; new message types can be added in seperate modules.
 - Easy to use; publishing and subscribing are straightforward
 - Consistent memory management; all message bus objects are AO2
   managed objects, using ao2_ref() and ao2_cleanup() to manage the
   reference counting.

In addition to basic publish/subscribe, the patch also provides a
mechanisms for message forwarding, and for message caching.

This addresses bug ASTERISK-20959.
