Taken out of our Xcode8 post-mortem: it's easy to forget (while adding)
or miss (while auditing) a `[Async]` attribute on the API that would
benefit from them.
API that are decorated with either:
* [Obsolete] (managed); or
* [Obsoleted] or [Deprecated] (native)
are not to be added *Async methods (or at least be reported as missing)
This also includes updated introspection tests that found the missing *Async API., ensuring that future API addition will immediately notice is an `[Async]` sounds useful.
Both are our own creation and can be worked around with the `Delegate`
and `DataSource` properties (or the `Weak` ones).
We'll revisit this for `XAMCORE_4_0` as the test will fail again.
With this commit the remaining failures for tvOS should all be fixed
[FAIL] `UICollectionView.get_Source` return type `UICollectionViewSource` is a concrete type `[Model]` and not an interface `[Protocol]`
[FAIL] `UICollectionView.set_Source` includes a paramater of type `UICollectionViewSource` which is a concrete type `[Model]` and not an interface `[Protocol]`
[FAIL] `UITableView.get_Source` return type `UITableViewSource` is a concrete type `[Model]` and not an interface `[Protocol]`
[FAIL] `UITableView.set_Source` includes a paramater of type `UITableViewSource` which is a concrete type `[Model]` and not an interface `[Protocol]`
Those tests needs to be run with the linker disabled since they use
reflection for most of their work.
The original dontlink (for linker tests) was becoming too large in
some configuration (e.g. tvOS release with bitcode) but this was
due to other BCL assemblies (not the introspection tests)
