PATCH: Consistent use of the noduplicate attribute

[James Molloy]

Hi Eli,

Sorry I didn't get to this very quickly. The patch in general looks fine
but I don't agree with removing setCannotDuplicate(). Many users of
noduplicate (for example OpenCL stacks) are out of tree, and I don't think
it's right to make an interface unorthogonal (getter but no setter) when
it's so simple just because there are no users in tree.

I'd appreciate if that could be added back in!

Cheers,

James
