2d778434f1 Enable cmake CMP0077 policy 
When building OpenCV as a sub-project using cmake's add_subdirectory()
the OpenCV's build options would be overwritten to its default
state. With cmake 3.13+ the CMP0077 policy, option() honors previous
definitions via set().

178c4810e6 Fix swapped channels in BGR* conversion utility function 
- some of `icvCvt_BGR*` functions have R with B channels
  swapped what leads to the wrong conversion
- renames misleading `rgb` variable name to `bgr`
- swap back the conversion coefficients, `cB` should be the first

c1cdb2416a imgproc(resize): improve 8u3 HResize vector exit calc 
Actually, we can do this in constant time. xofs always
contains same or increasing offset values. We can instead
find the most extreme value used and never attempt to load it.

Similarly, we can note for all dx >= 0 and dx < (dwidth - cn)
where xofs[dx] + cn < xofs[dwidth-cn] implies dx < (dwidth - cn).

Thus, we can use this to control our loop termination optimally.

This fixes #16137 with little or no performance impact. I have
also added a debug check as a sanity check.
