* Reworked phantom reference handling. - Replaced IDecRefQueue with a new Z3ReferenceQueue class - Z3ReferenceQueue manages custom subclasses of phantom references in a doubly-linked list - Replaced all subclasses of IDecRefQueue with subclasses of Z3ReferenceQueue.Reference. These custom reference classes are embedded in the class they reference count. - Context now owns a single Z3ReferenceQueue for all types of references. * Made Statistics.Entry a static subclass * Made Context.close idempotent (as recommended) * Update CMakeLists.txt for building the Java API. * Updated CMakeLists.txt again. * Use correct SuppressWarning annotation to silence the compiler * Formatting
