The color temperature member of the image object was named "col" in the
past. Now it is named "color" (which is still not very expressive).
There are still a few unspotted accesses to the col member. Fix them to
access the color member.

To be able to use the awb function copied from the Raspberry Pi tuning
scripts in the libtuning code, we need to remove the Cam object. Use the
logging framework to replace all accesses to Cam.log.

Tuning fails for raw images that don't have the channels ordered in
RGGB. In 19dc8c28f6 ("utils: tuning: libtuning: Implement the core of
libtuning") the channels of the image were reordered to RGGB
unconditionally in _read_image_dng(). That change was not applied to the
ctt_awb code, so that the channels were reordered twice. Fix by removing
the double ordering.

In the Image class the variable holding the color temperature is named
color instead of col which was used by the raspberry pi scripts. Rename
accordingly.

Copy ctt_{awb,ccm,colors,ransac} from the raspberrypi tuning scripts as

ctt_colors.py to better express the origin.
