Basically need to :
- Set the kernel parameter at each kernel invocation
- Modify the kernel to deal with wrap-around when writing the
waterfall texture
The batch size still must meet some constraint :
- Be a multiple of FOSPHOR_FFT_MULT_BATCH
- Be less than FOSPHOR_FFT_MAX_BATCH

Apparently there are some cards that are neither Nvidia SM1.1, nor
OpenCL 1.1 but that do have cl_khr_local_int32_base_atomics extension.
This is enough for fosphor to implement the histogram so add the
required code to test for it and enable its use in the kernel if
required.

The .pc has several libraries listed but the current cmake module for
it only takes gnuradio-runtime.
The new logic takes all libraries in the .pc and only fallsback to only
gnuradio-runtime if no .pc is found
This seems required for OSX.

OSX doesn't allow query of NV attributes even on NVidia cards so we just
assume any non-opencl 1.1 nvidia card that does OpenCL is a SM1.1 one.
