These patches came from the desire to propagate MODULE_STATE_COMING errors. While looking at that I spotted fail with a number of module notifiers themselves and with the whole notification business.
I will probably add a notifier for MODULE_STATE_UNFORMED, but that is later. Fixing this error propagation fixes a fairly serious (but really uncommon) bug when memory allocation fails for jump-labels while loading a module. And since we're going to be introducing more of that (static_call), fix it now.
