accel/cuda: add new accel module for NVidia GPU devices 



Current version allows offloading of xor/copy/fill operations.
It may be used for acceleration of xor ops for raid5f, etc.
Other accel ops to be implemented in the module later:
- Compare, crc32c, dif/dix, etc.
Use configure --with-cuda to enable the module.
