216baf5b11 Speedup of arcLength 
By my tests, this version of cv::arcLength is almost 10% faster than the
one using a buffer it replaces.

e837d69f8f IPPInitSingelton was added to contain IPP related global variables; 
OPENCV_IPP env var now allows to select IPP architecture level for IPP9+;

62854dcc0d Enables support of IPP 9.0.0; 
HAVE_IPP_ICV_ONLY will be undefined if OpenCV was linked against ICV packet from IPP9 or greater. ICV9+ packets will be aligned with IPP in OpenCV APIs
This will ease code management between IPP and ICV

3c85200989 Avoid negative index for a local buffer in Canny.cl. 
int pix_per_thr = l_counter / LOCAL_TOTAL + ((lid < mod) ? 1 : 0);
The pix_per_thr * LOCAL_TOTAL may be larger than l_counter.
Thus the index of l_stack may be negative which may cause serious
problems. Let's skip the loop when we get negative index and we need
to add back the lcounter to keep its balance and avoid potential
negative counter.

c5552788c5 Use vload to read unaligned data instead of dereference operator. 
According to opencl 1.2 spec 6.1.5:
    For arguments to a __kernel function declared to be a pointer to a
    data type, the OpenCL compiler can assume that the pointee is always
    appropriately aligned as required by the data type. The behavior of
    an unaligned load or store is undefined, except for the
    vloadn, vload_halfn, vstoren, and vstore_halfn functions defined in
    section 6.12.7.

Original code read data of type T from address not aligned by multiple
of sizeof(T), so the result is incorrect. With this patch, the cases
./opencv_perf_imgproc
--gtest_filter=OCL_ImgSize_TmplSize_Method_MatType_MatchTemplate.MatchTemplate/*
could work well with beignet 0.9.3.

d25770ee76 Fix Python 2 bindings for findContours 
The sanity check prevents Python 2 from calling findContours, because the
Python 2 bindings pass an empty matrix for `_contours`. If `_contours` is not
empty, the channel and depth check should determine whether the matrix is of
the correct type and size.

Note: the Python 2 bindings passes a matrix of type `STD_VECTOR_MAT` to
parameters of the type `OutputArrayOfArrays`.
