QDebug qt_QMetaEnum_debugOperator	(	QDebug &	dbg,

Formats the given enum value for debug output.

The supported verbosity are:

0: Just the key, or value with enum name if no key is found:

MyEnum2 MyEnum(123) MyScopedEnum::Enum3 MyScopedEnum(456)

1: Same as 0, but treating all enums as scoped:

MyEnum::MyEnum2 MyEnum(123) MyScopedEnum::Enum3 MyScopedEnum(456)

2: The QDebug default. Same as 0, and includes class/namespace scope:

3: Same as 2, but treating all enums as scoped:

void qt_QMetaEnum_flagDebugOperator	(	QDebug &	debug,

Specialization of the primary template in qdebug.h to out-of-line the common case of QFlags<T>::Int being int.

Just call the generic version so the two don't get out of sync.
