C API functions like PyDict_GetItem() and PyObject_HasAttr() suppresses all errors that may occur, including MemoryError and KeyboardInterrupt. They can return incorrect result when the memory is exhausted or the user presses Ctrl-C. The proposed PR documents such functions and suggests the C API which do not swallow unrelated exceptions.
Previous attempt to document this (for PyDict_GetItem() only) was in bpo-20615.

There are too much differences in the C API and the documentation between 3.x and 2.7, so backporting to 2.7 is not practical.
