Fabrice Fontaine c23612b5db package/opencv4: new package
opencv4 is not fully backward compatible with opencv3 as "a lot of C API
from OpenCV 1.x has been removed.": https://opencv.org/opencv-4-0.

Moreover, it should be noted that layout of include files as well as
pkg-config filename changed since
a956732874

All these changes mean that most of buildroot packages (e.g. vlc,
ffmpeg) are not compatible with opencv4.

Here is the most important changes between opencv3 and opencv 4.5.1:
 - License is Apache-2.0 (https://opencv.org/opencv-4-5-0)
 - openjpeg is an optional dependency (enabled by default) since
   0384eb7d8c
   jpeg2000 can be enabled through openjpeg or jasper
 - pkg-config must be enabled with OPENCV_GENERATE_PKGCONFIG since
   e755a2a6e4
 - cmake is not installed in /usr/share anymore so hook can be dropped
 - C++11 is required since
   d4688e6474
