ee940b130f retinex: Port to GstOpencvVideoFilter base class
This allow reducing slightly the code. It also fixes a bug caused by
in-place buffer being mapped and never unmapped.

447c1b1395 opencv: clean includes
The opencv element includes were full of duplicates and uneeded headers.
For example a few elements that stopped using gstcvopencvutils still
included that header file.

45d9184c88 opencv: use gst_opencv_video_filter_set_in_place()
Using the gst_base_transform function directly won't work. Need to use
gst_opencv_video_filter_set_in_place().

589407a077 opencv: Change opencv plugin to use opencv2-style includes
If old opencv1-style legacy include directory is available,
this change becomes purely cosmetic (maybe will compile a bit faster).
It becomes an FTBFS fix when opencv1-style include directory is missing
(possibly because opencv package maintainer decided not to pack it).

407f3e1856 opencv: Add colour image enhancement element based on Retinex algorithm
Add colour image enhancement element based on Retinex algorithm. Two types
exist, namely basic and multiscale; both are described in this article:

Rahman, Zia-ur, Daniel J. Jobson, and Glenn A. Woodell. "Multi-scale retinex
for color image enhancement." Image Processing, 1996. Proceedings.,
International Conference on. Vol. 3. IEEE, 1996

Visually speaking the result looks a bit funny, but is pretty invariable to
lightning changes, which is good for some applications, like image
segmentation.
