New Revision: 214193

URL: http://svn.asterisk.org/svn-view/asterisk?view=rev&rev=214193
Log:
Progress towards starting up the core.

It compiles. That's all I'm going to say. I need
to define the agent more fully. I'm pretty sure
it'll end up being refcounted since, especially
with native agents, multiple threads will need
to refer to a single agent.
