Call display tweaks
I'm not completely sure if the problem I try to address in the second commit is really a problem. Basically I was wondering if it were possible that the property binding becomes stale and I think it can in the following scenario
*_set_call (display, call)
-
*_set_call (display, NULL)
with the oldcall
still being alive
The last commit is WIP because I'm not a 100% sure what would be a sensible thing to display (I assume that we don't want the CuiCallDisplay to be displayed at all if call == NULL
?!)
