Summary:                    [branch] Asterisk blocked when 2 or more users leave
a meetme when announce user is on
Description: 
If option I is used with meetme and 2 or more participants leave a
conference simultaneously, Asterisk stops working properly.  As the number
of simultaneous users leaving increases, the affect on Asterisk is
increased.

When the users hangup, zap channels stop accepting calls until the "user
has left the conference" message has played.  When several users leave
simultaneously the dialplan stops executing.
console commands such as meetme and core show channels will stop working. 
Sometimes the response is delayed by a few seconds and sometimes nothing is
returned at all.

When a larger number of users disconnect at the same time, Asterisk
becomes completely unusable without a restart

(closes issue http://bugs.digium.com/view.php?id=13173)
Reported by: pep

This change adds an announce_thread responsible for playing announcements
to an existing conference. This allows all announcing to be immediately
stopped if necessary but more importantly allows other threads that need to
play something to not block. There are multiple benefits to this, but the
actual bug is for solving the scenario for a channel to be unusable after
hang up for the entire duration of the parting announcement. The parting
announcement can be extremely long depending on what the user recorded upon
joining the conference.
