[issue10868] ABCMeta.register() should work as a decorator

[Edoardo Spadolini]

New submission from Edoardo Spadolini <kerio00 at gmail.com>:

If we make ABCMeta.register() return the registered class, like atexit.register() does for the registered function, we can then use it as a decorator:

Now:

class Foo:
    ...
ABarC.register(Foo)

With this change:

@ABarC.register
class Foo:
    ...

The only problem this would cause is in code that relies on ABCMeta.register() to return None; I can't think of a reason anyone would rely on this, but...
