2018-05-25media: docs: clarify relationship between crop and selection APIsLuca Ceresoli4-10/+20
Having two somewhat similar and largely overlapping APIs is confusing, especially since the older one appears in the docs before the newer and most featureful counterpart. Clarify all of this in several ways: - swap the two sections - give a name to the two APIs in the section names - add a note at the beginning of the CROP API section - update note about VIDIOC_CROPCAP Also remove a note that is incorrect (correct wording is in vidioc-cropcap.rst).

For the files written with a copyright with mchehab@s-opensource, let's keep Samsung on their names, using mchehab+samsung@kernel.org, in order to keep pointing to my employer, with sponsors the work. For the files written before I join Samsung (on July, 4 2013), let's just use mchehab@kernel.org.
