There was a misunderstanding of what the CUDA traits really stood for. This wasn't helped by the fact that the NVIDIA CUDA documentation and versioning system is so awkward. Basically, there's the CUDA Compute Capability version, which represents the hardware GPU instruction set extensions supported by various NVIDIA GPUs. And there is the CUDA SDK version which represents a window of CUDA Compute Capability versions that the library is able to work with. This patch adds a new os_traits.hw.gpu.cuda module with these new traits. It removes the old os_traits.hw.gpu.api.CUDA* traits since those were misleading and inaccurate. It also adds a new utility function that maps CUDA SDK version to supported CUDA Compute Capability versions that the SDK supports. This support matrix information was taken from the CUDA wikipedia article which lists the supported version information. Change-Id: Id4adb6874615ad5f9f8aff780a83119e10a38c35
