Initial commit for Conjugate Gradient method

Implementation is based on
http://www.cs.cmu.edu/~quake-papers/painless-conjugate-gradient.pdf

So far we only have basic interface and empty test. But it compiles at
least.
Refined interface for Conjugate Gradient

Some interface was refined (most notably, the method for returning
Hessian was removed and the method for getting gradient was added as
optional to base Solver::Function class) and basic code for
setters/getters was added. Now is the time for the real work on an
algorithm.
switched to new device layer in gpucodec module
If device does not support double, returns immediately.
Double floating points are not default supported by OpenCL.
fixed ocl::minMax
fixed ocl::countNonZero
Finish implementing the Nonlinear Conjugate Gradient

Now everything is prepared for the pull request.
Minor fixes

Fix failed builds that opencv's buildbot has got.
Make libv4l support optional for testing purposes.
Applied fix suggested in bug 3282 and shortened code
Added the copyright statements

Added the copyrights missing in all files that required so.
fixed ocl::sum, ocl::sqrSum, ocl::absSum
fixed ocl::phase
