Accept keyword arguments accessing C++ static member functions when
using -builtin and kwargs feature and Python class staticmethod syntax.
The missing keyword argument support was only when using the
class staticmethod syntax, not when using the flat static method
syntax.
Use Python class staticmethod syntax to access C++ static member functions,
such as Klass.memberfunction, instead of Klass_memberfunction.
Examples and test-suite changes in preparation for issue #2137.
The fix is when using kwargs feature or -keyword.
The fix is in the argument error checking when wrapping zero
argument constructors only. Supplied keyword args were silently
ignored.
Issue #1595
