Bug 1144 - Add 'DelegateImplementation': Cleanup JavaConfiguration and use manuallyImplement(AliasedSymbol) for FunctionSymbol
 (commit: 454fac4)

Bug 1144 - Add 'DelegateImplementation': Sort JavaMethodBindingEmitter argument list; forImplementingMethodCall -> isNativeMethod
 (commit: c3b2a86)

Bug 1144 - Add 'DelegateImplementation': Cleanup MethodBinding/FunctionBinding Semantics

- Clarify name semantics: name -> [interfaceName, implName, nativeName]
- JavaMethodBindingEmitter: Refine native identity via isNativeMethod + isPrivateNativeMethod
- ProcAddressEmitter: Remove hack whether we need to wrap .. use isNativeMethod + isPrivateNativeMethod

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>.

Bug 1134 - LOG AliasedSymbol: Don't issue getAliasedString(), logger takes care of that, when it logs.
 (commit: 25f2486)

Bug 1144 - Add 'DelegateImplementation': Requires own MethodBinding for delegates impl. / Adding ReturnsOpaque

- DelegateImplementation requires own MethodBinding for delegates impl.
  The delegation name must be included within
  the FunctionSymbol's aliases _only_ for implementations,
  where delegation applies.
  This allows all subsequent type/cfg checks to hit on AliasedSymbol!

  Hence we need to create individual MethodBinding instances
  for interfaces and public/private implementations.

- Adding ReturnsOpaque
  Configuration:
    ReturnsOpaque <Primitive Java Type> <Function Name>

  This feature is necessary to achieve 'Opaque' functionality
  for function's return type - instead of types in general.

- Fix AliasedSymbolImpl copy-ctor, i.e. this.name = o.name !
