[ofw] [RFC] [PATCH 3/4] index list: new component to map quickly from an index to a pointer

I changed it to IndexListRemoveHead().

There is a doubly-linked list that's being maintained, and the item being
removed is at the head of that list.  It's not necessarily the item that was
inserted last, but whatever item ended up at the head.  Since items can be
removed in the middle of the list, it doesn't match the behavior of a stack.

Now, if you want to argue that IndexListInsert() would be better named
IndexListInsertHead()...
