Bug 1144 - Add 'DelegateImplementation', manually impl. may delegate to renamed original

'DelegateImplementation' is a variation of 'ManuallyImplement'.

'ManuallyImplement' emits the interface method, but suppresses
the Java and native-code implementation.
The latter shall be implemented manually by the user.

'DelegateImplementation' emits the interface method,
and the _private_ renamed Java and native-code implementation.
Both can be called from the manual user implementation,
hence delegation.

Configuration:
  DelegateImplementation <ORIG-SYMBOL> <RENAMED-IMPL-SYMBOL>

I.e. delegation model shall apply to <ORIG-SYMBOL>
and the Java and native-code implementation renamed to <RENAMED-IMPL-SYMBOL>.

The user manual implementation of <ORIG-SYMBOL>
may delegate to <RENAMED-IMPL-SYMBOL>.
