This patch makes it so that all queue member status changes are handled through device state
code. This removes several problems people were seeing where their queue members would get into an "unknown" state. Huge props go to atis on this one since he was the one who found the code section that was causing the problem and proposed the solution. I just wrote what he suggested :) (closes issue #12127) Reported by: atis Patches: 12127v3.patch uploaded by putnopvut (license 60) Tested by: atis, jvandal git-svn-id: https://origsvn.digium.com/svn/asterisk/branches/1.4@109713 65c4cc65-6c06-0410-ace0-fbb531ad65f3
