Frames from the inbound channel should go to all outbound channels in app_dial.c.

In app_dial.c:wait_for_answer() frames from the inbound channel should be
sent to all outbound channels instead of only if there is just one
outbound channel.

Control frames like AST_CONTROL_CONNECTED_LINE need to be passed to all of
the the outbound channels.  This can happen if a blond transfer is done by
a remote switch on the inbound channel.
