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. ;=]

Replaced most of the usages of parallel_for with that of parallel_for_.
...
This should allow many algorithms to take advantage of more parallelization
technologies.

Fix equalization formula in equalizeHist function & rewrite in C++
...
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)
