Log Message:
-----------
modules/dialog: Provide new fix to prevent "unable to find
dialog" WARN messages caused by accessing a dialog in the
"deleted" state (often happens with simultaneous BYE requests when
both UAs hang up at the same time).

This commit uses a different approach where a "deleted" flag is
set in get_dlg() and lookup_dlg() which callers may evaluate.
Callers who only care about existing dialogs can ignore the flag
by passing a NULL argument.

This revision "replaces" 6027.
