This reverts commit 3cf877c00d.
The issue with this commit is that it adds stubs for some methods
which are actually implemeneted in categories in Foundation. The good
parts of this commit will be later committed once those are removed.
-Werror is now enabled so there won't be any more in the future.
Places I noticed that had stubs which didn't have it now print a
message indicating that a stub was called.
