The rebased patch includes the following changes:

- `apply_to` and `apply_only_to` are merged into one `apply_to` specifier with `apply_only_to` semantics.
- The subject match rule list that's supported by an attribute is now reported in the fix-it for some of the parse diagnostics.
- GNU style attributes must now use `__attribute__`` syntax.
- `__declspec` attributes are now supported.
- Errors and warnings are now always emitted for each receiving declaration.
- The compiler now warns about unused attributes.
- The compiler now warns about unterminated pushes.
- Objective-C categories are now supported as well.

I couldn't find a good/suitable way to include the attribute subject match rule list that's supported by an attribute in the documentation. Maybe we could specify these lists in a new document?
