This reverts commit fba72cb6, reversing
changes made to 02131ffb.

e.g. <opencv2/core/core.hpp> become <opencv2/core.hpp>

Also renamed <opencv2/core/opengl_interop.hpp> to <opencv2/core/opengl.hpp>

* reorder arguments
* rewrite accuracy tests
* replace doubles with integer arithmetic inside the main loop

All the functions from it are moved to the header
opencv2/photo/photo.hpp

enabled SSE3 by default; integrated SSE3-optimized bilateral filter (by Grigoriy Frolov); modified API of non-local means (use Input/OutputArrays)

moving the rest of inpaint() to the 'photo' module, temporary disabling Java test for it, adding 'photo' to Java API

lot's of changes; nonfree & photo modules added; SIFT & SURF -> nonfree module; Inpainting -> photo; refactored features2d (ORB is still failing tests), optimized brute-force matcher and made it non-template.
