Bugfix for an overlapping size of image and template for matchTemplate.
...
Example: img of size 10x10 and templ of size 11x9.
In subsequent code this will results in either width or height of
corrSize to be zero (0).
Line 261 will call crossCorr which will then have a zero size of either
blocksize.width or blocksize.height resulting in a division by zero
crach in lines 137 or 138.

Split CLAHE into its own file, because it's faster that way.
...
Yes, it's as ludicrous as it sounds, but it's still true. Bizarrely,
the previous commit makes CLAHE run about 10% slower on Android, even
though it doesn't even touch any CLAHE code. Splitting it off fixes that,
although the reason it does is a mystery for the ages.
It's cleaner when it's in its own file, anyway. ;=]

Changed convexHull's documentation to essentially invert the meaning of ``clockwise``.
...
The orientation of convexHull's result is currently the opposite of what the
documentation would suggest:
>>> import cv2, numpy as np
>>> points = np.array([[0,0],[0,1],[1,0]], dtype=np.int32)
>>> cv2.convexHull(points, clockwise=False)
array([[[1, 0]],
[[0, 1]],
[[0, 0]]], dtype=int32)
>>> cv2.convexHull(points, clockwise=True)
array([[[0, 0]],
[[0, 1]],
[[1, 0]]], dtype=int32)
Changing the function itself is probably not a good idea at this point, so
this fixes the documentation by flipping the coordinate system.
I also removed the mention of the origin, since it's irrelevant for this
function.

Old implementation did
lut[i] = 255 * (count(Y <= i)) / (width * height)
which actually shifts uniform histograms.
From now histogram is equalized as
C = count(Y == min(Y))
lut[i] = 255 * (count(Y <= i) - C) / (width * height - C)
