Bug 1134 - Enhance GlueGen Compiler: Minimal GL Header Changes _and_ Typesafety

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

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

  - GlueGen now detects function redefines (overloading)
    and throw an exception in this case.
    Hence the semantics of duplicate functions has to be equal!
    This helps detecting wrongly renamed GL extensions into core!

  - Semantic equality for all types is provided
    via interface TypeComparator.SemanticEqualityOp, i.e. 'boolean equalSemantics(..)'
    implemented by com.jogamp.gluegen.cgram.types.Type.

    Semantic equality can be relaxed via config "RelaxedEqualSemanticsTest true",
    i.e. ignoring integer size, and const / volatile qualifiers.

  - All equality/hash methods of 'com.jogamp.gluegen.cgram.types.*'
    are restructured.

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

  - This is provided in a unified manner
    via interface com.jogamp.gluegen.cgram.types.AliasedSymbol
    and its common implementation AliasedSymbolImpl

  - All JavaConfiguration.shouldIgnore* methods operate w/
    'AliasedSymbol' trying to match all aliases.

- Support 'struct NAME [ { ... } ]' w/o typedef's
  - New GL / CL headers do not use typedef's for anonymous opaque types

- Opaque Type handling
  - JavaConfiguration.typeInfo(..), identifying opaque types,
    no more back references from target-type -> typedef.
    Hence the following is possible now:
      typedef void * Opaque01; // Opaque
      typedef void * APointerBuffer; // A Buffer

- All Logger instances are no more static
  and derive their warning level from the package's root Logger
  via Logging.getLogger(..).
