Bug 1134

- We shall be able to import 'most' vanilla GL header,
  i.e. only change the typedef part using our GlueGen types

- Type Safety:
  - GlueGen shall detect '#define' and 'enum' redefines 
    and throw an exception in this case.
    This helps detecting wrongly renamed GL extensions into core!

  - The same goes for function symbols, 
    i.e. their semantics have to be equal!
    This helps detecting wrongly renamed GL extensions into core!

  - Hence semantic equality shall be validated

- Track and simplify renamed 'symbol', i.e. use a common 
  sub-interface for all renamed symbols (ConstantDefinition, FunctionSymbol, ..).
