[Guile] New runtime functions SWIG_PointerAddress,
SWIG_PointerType, SWIG_IsPointerOfType, SWIG_IsPointer.
[Guile] In -scm mode, wrap several SWIG runtime functions
and export them into the module (Swig swigrun). The
runtime module is now built with "module" linkage.
[Guile] GOOPS proxy objects now also print the pointer
address of the C object.
