opencv: Add cvcalchist element for calculating histogram

Updated the patch to apply on latest master.

Currently it acts as passthrough and analyzes the image but if
draw-histogram=true
it will push a buffer containing the histogram. Do we have any element with
similar
behavior or any standard way of doing this? 2 pads or a property?
