New Revision: 425072

Log:
chan_sip: Fix dialog leak resulting from missing ACK to re-INVITE.

If a device re-INVITEs at the same time as the dialog is hung up, and
if then the ACK to the re-INVITE never reaches Asterisk, chan_sip would
fail to destroy the dialog after a while.  This resulted in (most
prominently) file handle leaks.

(Patch reindented by me.)
