Additional macros for modules that implement new object types.
You must first include "object.h".
NEWOBJ(type, typeobj) allocates memory for a new object of the given
type; here 'type' must be the C structure type used to represent the
object and 'typeobj' the address of the corresponding type object.
Reference count and type pointer are filled in; the rest of the bytes of
the object are *undefined*! The resulting expression type is 'type *'.
The size of the object is actually determined by the tp_basicsize field
of the type object.
NEWVAROBJ(type, typeobj, n) is similar but allocates a variable-size
object with n extra items. The size is computer as tp_basicsize plus
n * tp_itemsize. This fills in the ob_size field as well.
