What's the point? The codecs functions already support objects exposing the buffer interface:

>>> b = b"\xe9"
>>> codecs.latin_1_decode(memoryview(b))
('é', 1)
>>> codecs.latin_1_decode(array.array("b", b))
('é', 1)

Those two functions are undocumented. They serve no useful purpose (you can call the bytes(...) constructor instead, or even use the buffer object directly as showed above). They are badly named since they don't have anything to do with codecs. Google Code Search shows them not appearing anywhere else than implementations of the Python stdlib. Removing them only seems reasonable.
