Author: kpfleming

New Revision: 106945

URL: http://svn.digium.com/view/asterisk?view=rev&rev=106945
Log:
don't generate D-Channel "up" and "down" messages unless the channel state is actually changing; also, generate the "up" message when an implicit "up" occurs due to reception of a normal event when we thought the channel was "down"
