Add support for __repr__ in QObject derived classes
Currently shiboken generates classes without __repr__ for QObject
derived classes. However for all non-QObject classes that have an
operator<<() for QDebug, it *does* add a valid repr implementation.
Extend this behavior to QObject classes as well.
In order for this to become more useful, also check for the indirection
of operator<<(): If operator<<(QDebug, Foo*) is available, use the
current non-value-type behavior, (i.e. provide cppSelf to operator<<()),
but if operator<<(QDebug, const Foo&) is available instead, use the same
behavior as for value-types, i.e. provide *cppSelf.
This greatly increases the number of classes where operator<<() provides
useful results.
Also make sure to check for operator<<() in namespaces (recursively),
not just at global scope.
