New Revision: 38077

URL: http://svn.digium.com/view/asterisk?rev=38077&view=rev
Log:
use ast_atomic_fetchadd_int in chan_zap, sip, and iax2 for usecount handling
and fix a couple little things in passing
 - usecnt was not initialized in chan_iax2
 - ast_update_use_count() was not called after incrementing the count in chan_sip
