Fix random crashes when using the MeetMe application. This patch converts list
handling to use the linked list macros and most importantly, implements reference counting on the ast_conference objects. The reference counting was first backported from 1.4. However, that code has some problems that caused the reference count to never hit zero. Those problems are fixed in this patch and will be resolved in 1.4 and trunk next, with a different patch. (issues #7647, #9073, #9106, BE-115). git-svn-id: http://svn.digium.com/svn/asterisk/branches/1.2@55750 f38db490-d61c-443f-a65b-d21fe96a405b
