DeferredList errors

Description (last modified by Bryan Forbes)

I have found three big bugs:

  1. DeferredList? throws an error about _cbDeferred not being a function. This is because there is no scope given on the addCallback and addErrback in lines 30 and 31.
  1. The original callbacks don't get anything to their arguments because the addCallback and addErrback functions in lines 30 and 31 don't return anything.
  1. The DeferredList?'s callback is fired before the last deferred's callback is called.

I have attached a patch that fixes 1 and 2. I also simplified the forEach loop in the process. This, however, does not fix 3. I added a unit test file with two tests. The first (if run before the patch to DeferredList?.js) shows 1 and 2. The second shows 3.

Not sure why this got assigned to me, I think it belongs to either dmachi or alex.

1 has already been fixed in a checkin earlier today. 3 is the spec'd behavior (the callbacks are attached to the callback chain of the individual deferreds at the time the list is created. I'll incorporate your changes for 2.

(In [10784]) fixes deferred list return problem. fixes #4240 execept issue 3 which is the expected behavior though admittedly can be confusing at times.
