Log Message:
-----------
Added file libicv/color_space.c . This will contain all the color_space
conversion api functions (currently rgb-gray and gray-rgb, later others like
hsv-rgb, cmyka-rgb etc..). Added gray2rgb api function. This does a simple gray
pixel copying at three places(r,g,b). This api function does an inplace
color_space change.
