SI-8954 Make @deprecated{Overriding,Inheritance} aware of @deprecated.
This makes sure that:
- there is no warning for a @deprecated class inheriting a
@deprecatedInheritance class
- there is no warning for a @deprecated method overriding a
@deprecatedOverriding method
- there is no "deprecation won't work" warning when overriding a member
of a @deprecatedInheritance class with a @deprecated member
- the above works even if the classes/methods are indirectly deprecated
(i.e. enclosed in something @deprecated)
This should remove quite a few useless deprecation warnings from the
library.
