Revert "Fix T68971: Copy As New Driver from Material node creates a bad reference."

This reverts commits 54fd8176d7e91, 4c5becb6b1 and 8f578150e.

Those kind of commits must be reviewed and approved by project owners.

That one:
* Broke Collada building by not properly updating all calls to modified
function.
* Broke *whole* ID management by not properly updating library_query.c.

And in general, I am strongly against backward ID pointers, those are
*always* a serious PITA for ID management. Sometimes  they cannot be
avoided, but in general other ways to get that kind of info should be
investigated first.
