cl-wdr: optimize new tonemapping algorithm
* Optimzied new tonemapping algorithm based on novel histogram adjustment.
Add a recursive function to binary partition the histogram and optimize the
performance.
* Test command line:
./tests/test-device-manager -a dynamic -m dma -c --enable-new-wdr -d still -p

cl-wdr: New wdr algorithm based on histogram
* Command line option only works for local preview currently.
* Seperate handler and kernel files. Independent of other kernels.
* Test command line for new wdr algorithm in local preview:
./tests/test-device-manager -a dynamic -m dma -c --enable-new-wdr -d still -p
* Test command line for original algorithm doesn't change:
./tests/test-device-manager -a dynamic -m dma -c --enable-wdr -d still -p
