Updated patch:

1, Changes follows review comments: http://codereview.appspot.com/4185044/. Thanks eric!

2, Make Objects/dictobject.c:all_contained_in() a common useful limited api Object/abstract.c:_PyObject_AllContainedIn() for the purpose of re-usage in Modules/_gdbmmodule.c and Modules/_dbmmodule.c. Not sure if this is proper. I will ask somebody with C knowledge to do a review on the C code.
