The functionality of dict.setdefault() is not currently available through the C-API. Specfically, there is no way to test for a key and insert a fallback value for it without evaluating the hash function twice.

The attached patch adds a new C-API function PyDict_GetItemSetDefault() that makes this feature available. Like all PyDict_Getitem*() functions, it returns a borrowed reference.

I hope I got the update in refcounts.dat right. I have no idea how to express that a function *may* increase the refcounts of its arguments.
