Denotes that the annotated method can be called from any thread (e.g. it is
"thread safe".) If the annotated element is a class, then all methods in the
class can be called from any thread.

The main purpose of this method is to indicate that you believe a method can
be called from any thread; static tools can then check that nothing you call
from within this method or class have more strict threading requirements.

Example:

 @AnyThread
 public void deliverResult(D data) { ... }


@memberDoc
This method is safe to call from any thread.
@hide
