[arch-general] The OpenCL ICD problem

[Vojtěch Král]

@Ionut, Lukas:
  I support this proposal too and I'd agree that only the libOpenCL.so
(the ICD loader)
needs to be split off nvidia-utils. Otherwise it could just stay
intact as far as I can tell...

Also, it would probably be wise to settle for dependency names once for all,
by dependency names I mean what the pkgs provide - right now, all
OpenCL pkgs provide
both 'opencl' and 'libcl'. So following your proposal, 'libcl' could
be provided by the loader,
while 'opencl' could be provided by opencl implementations. Or
something along those lines...

@Nicolas:
  That looks great. If you released that as opensource,
it'd probably be a better choice over the clinfo by Amd.
