Blank module and first draft of solver API.

At this point we have a skeleton of a new module (optim) which can
barely compile properly (unlike previous commit). Besides, there is a
first draft of solver and lpsolver (linear optimization solver) in this
commit.

-Denoising
-==========
-
-.. highlight:: cpp
-
-fastNlMeansDenoising
---------------------
-Perform image denoising using Non-local Means Denoising algorithm http://www.ipol.im/pub/algo/bcm_non_local_means_denoising/
-with several computational optimizations. Noise expected to be a gaussian white noise
-
-.. ocv:function:: void fastNlMeansDenoising( InputArray src, OutputArray dst, float h=3, int templateWindowSize=7, int searchWindowSize=21 )
-
-    :param src: Input 8-bit 1-channel, 2-channel or 3-channel image.
-
-    :param dst: Output image with the same size and type as  ``src`` .
-
-    :param templateWindowSize: Size in pixels of the template patch that is used to compute weights. Should be odd. Recommended value 7 pixels
-
-    :param searchWindowSize: Size in pixels of the window that is used to compute weighted average for given pixel. Should be odd. Affect performance linearly: greater searchWindowsSize - greater denoising time. Recommended value 21 pixels
-
-    :param h: Parameter regulating filter strength. Big h value perfectly removes noise but also removes image details, smaller h value preserves details but also preserves some noise
-
-This function expected to be applied to grayscale images. For colored images look at ``fastNlMeansDenoisingColored``.
-Advanced usage of this functions can be manual denoising of colored image in different colorspaces.
-Such approach is used in ``fastNlMeansDenoisingColored`` by converting image to CIELAB colorspace and then separately denoise L and AB components with different h parameter.
-
-fastNlMeansDenoisingColored
----------------------------
-Modification of ``fastNlMeansDenoising`` function for colored images
-
-.. ocv:function:: void fastNlMeansDenoisingColored( InputArray src, OutputArray dst, float h=3, float hColor=3, int templateWindowSize=7, int searchWindowSize=21 )
-
-    :param src: Input 8-bit 3-channel image.
-
-    :param dst: Output image with the same size and type as  ``src`` .
-
-    :param templateWindowSize: Size in pixels of the template patch that is used to compute weights. Should be odd. Recommended value 7 pixels
-
-    :param searchWindowSize: Size in pixels of the window that is used to compute weighted average for given pixel. Should be odd. Affect performance linearly: greater searchWindowsSize - greater denoising time. Recommended value 21 pixels
-
-    :param h: Parameter regulating filter strength for luminance component. Bigger h value perfectly removes noise but also removes image details, smaller h value preserves details but also preserves some noise
-
-    :param hForColorComponents: The same as h but for color components. For most images value equals 10 will be enought to remove colored noise and do not distort colors
-
-The function converts image to CIELAB colorspace and then separately denoise L and AB components with given h parameters using ``fastNlMeansDenoising`` function.
-
-fastNlMeansDenoisingMulti
--------------------------
-Modification of ``fastNlMeansDenoising`` function for images sequence where consequtive images have been captured in small period of time. For example video. This version of the function is for grayscale images or for manual manipulation with colorspaces.
-For more details see http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.131.6394
-
-.. ocv:function:: void fastNlMeansDenoisingMulti( InputArrayOfArrays srcImgs, OutputArray dst, int imgToDenoiseIndex, int temporalWindowSize, float h=3, int templateWindowSize=7, int searchWindowSize=21 )
-
-    :param srcImgs: Input 8-bit 1-channel, 2-channel or 3-channel images sequence. All images should have the same type and size.
-
-    :param imgToDenoiseIndex: Target image to denoise index in ``srcImgs`` sequence
-
-    :param temporalWindowSize: Number of surrounding images to use for target image denoising. Should be odd. Images from ``imgToDenoiseIndex - temporalWindowSize / 2`` to ``imgToDenoiseIndex - temporalWindowSize / 2`` from ``srcImgs`` will be used to denoise ``srcImgs[imgToDenoiseIndex]`` image.
-
-    :param dst: Output image with the same size and type as ``srcImgs`` images.
-
-    :param templateWindowSize: Size in pixels of the template patch that is used to compute weights. Should be odd. Recommended value 7 pixels
-
-    :param searchWindowSize: Size in pixels of the window that is used to compute weighted average for given pixel. Should be odd. Affect performance linearly: greater searchWindowsSize - greater denoising time. Recommended value 21 pixels
-
-    :param h: Parameter regulating filter strength for luminance component. Bigger h value perfectly removes noise but also removes image details, smaller h value preserves details but also preserves some noise
-
-fastNlMeansDenoisingColoredMulti
---------------------------------
-Modification of ``fastNlMeansDenoisingMulti`` function for colored images sequences
-
-.. ocv:function:: void fastNlMeansDenoisingColoredMulti( InputArrayOfArrays srcImgs, OutputArray dst, int imgToDenoiseIndex, int temporalWindowSize, float h=3, float hColor=3, int templateWindowSize=7, int searchWindowSize=21 )
-
-    :param srcImgs: Input 8-bit 3-channel images sequence. All images should have the same type and size.
-
-    :param imgToDenoiseIndex: Target image to denoise index in ``srcImgs`` sequence
-
-    :param temporalWindowSize: Number of surrounding images to use for target image denoising. Should be odd. Images from ``imgToDenoiseIndex - temporalWindowSize / 2`` to ``imgToDenoiseIndex - temporalWindowSize / 2`` from ``srcImgs`` will be used to denoise ``srcImgs[imgToDenoiseIndex]`` image.
-
-    :param dst: Output image with the same size and type as ``srcImgs`` images.
-
-    :param templateWindowSize: Size in pixels of the template patch that is used to compute weights. Should be odd. Recommended value 7 pixels
-
-    :param searchWindowSize: Size in pixels of the window that is used to compute weighted average for given pixel. Should be odd. Affect performance linearly: greater searchWindowsSize - greater denoising time. Recommended value 21 pixels
-
-    :param h: Parameter regulating filter strength for luminance component. Bigger h value perfectly removes noise but also removes image details, smaller h value preserves details but also preserves some noise.
-
-    :param hForColorComponents: The same as h but for color components.
-
-The function converts images to CIELAB colorspace and then separately denoise L and AB components with given h parameters using ``fastNlMeansDenoisingMulti`` function.

-Inpainting
-==========
-
-.. highlight:: cpp
-
-inpaint
------------
-Restores the selected region in an image using the region neighborhood.
-
-.. ocv:function:: void inpaint( InputArray src, InputArray inpaintMask, OutputArray dst, double inpaintRadius, int flags )
-
-.. ocv:pyfunction:: cv2.inpaint(src, inpaintMask, inpaintRadius, flags[, dst]) -> dst
-
-.. ocv:cfunction:: void cvInpaint( const CvArr* src, const CvArr* inpaint_mask, CvArr* dst, double inpaintRange, int flags )
-
-    :param src: Input 8-bit 1-channel or 3-channel image.
-
-    :param inpaintMask: Inpainting mask, 8-bit 1-channel image. Non-zero pixels indicate the area that needs to be inpainted.
-
-    :param dst: Output image with the same size and type as  ``src`` .
-
-    :param inpaintRadius: Radius of a circular neighborhood of each point inpainted that is considered by the algorithm.
-
-    :param flags: Inpainting method that could be one of the following:
-
-            * **INPAINT_NS**     Navier-Stokes based method.
-
-            * **INPAINT_TELEA**     Method by Alexandru Telea  [Telea04]_.
-
-The function reconstructs the selected image area from the pixel near the area boundary. The function may be used to remove dust and scratches from a scanned photo, or to remove undesirable objects from still images or video. See
-http://en.wikipedia.org/wiki/Inpainting
-for more details.
