Summary:                    Asterisk Crashes in Function "retrans_pkt"
Description: 
We are seeing asterisk crash with what appears to be a race condition in
chan_sip, apparently around packet retransmission. A BT Full from asterisk
made with "don't optimize" is included. This appears related to, but
slightly different than 10256.

Fix some crashes in chan_sip.  This patch changes various places that add
items
to the scheduler to ensure that they don't overwrite the ID of a
previously
scheduled item.  If there is one, it should be removed.

http://bugs.digium.com/view.php?id=10256, probably others, patch by me)
