9be6b4f2d1 Bug Fix for 6377 
Rewrite linearPolar & logPolar so that they do not depend on the
deprecated API CvMat. Issue 6377 is resolved in this way because the two
routines do not convert UMat to CvMat anymore.

68d97502fe Error message for wrong kernel size was insufficient. 
When setting a wrong kernel size, the error message only tells the user that it
must be odd, however the conditions for rejection include values > 7 which must
be communicated. Without that, the message would be incorrect and confusing if
the user is unaware that only values 3, 5, 7 are accepted.

0b08d2559e fix potential race condition in canny.cl. 
See the below code snippet:

while(l_counter != 0)
{
    int mod = l_counter % LOCAL_TOTAL;
    int pix_per_thr = l_counter / LOCAL_TOTAL + ((lid < mod) ? 1 : 0);

    for (int i = 0; i < pix_per_thr; ++i)
    {
        int index = atomic_dec(&l_counter) - 1;
        ....
    }
    ....
    barrier(CLK_LOCAL_MEM_FENCE);
}

If we don't put a barrier before the for loop, then there is a possiblity
that some work item enter this loop but the others are not, the the l_counter
will be reduced in the for loop and may be changed to zero, and the other
work items may can't enter the while loop. If this happens, it breaks the
barrier's rule which requires all the work items reach the same barrier.
And it may hang the GPU depends on the implementation of opencl platform.

cc903d0605 Fix for #5590. OpenCL BilateralFilter implementation failes to 
build for some OCL drivers.
Some OCL vendors treat implicit scalar-vector conversions for
operators as errors when type conversion is required.
