e1f43e3b03 Add sort_by_key for oclMat. 
Most codes are ported from AMD's Bolt library.
Four methods are implemented:

SORT_BITONIC,   // only support power-of-2 buffer size
SORT_SELECTION, // cannot sort duplicate keys
SORT_MERGE,
SORT_RADIX      // only support signed int/float keys

e77abeef16 Add a new global function to control ocl binary storage 
Previously the feature is controlled by setBinpath implicitly.
We add the function to cope with setBinpath and setBinpath is only
useful when setBinaryDiskCache is set.
Refer to the header to see more info.

b1c248fcc9 Fix ocl::filter2D. 
In current implementation, this function only works when anchor point is
in the kernel center and kernel size supported is either 3x3 or 5x5.

fd7ba355ee Add non-stump based ocl Haar cascade classifier support. 
For example, haarcascade_frontalface_alt2.xml is now supported.
Note that classifier's pattern of a cascade file must be consistent,
i.e., all trees must either have two nodes or one node, otherwise
unexpected results will occur.

Other fixes:
Test cases are updated.
Some unused codes are removed.
Fix some problems of haar when using OclCascadeClassifierBuf.

b4a4a05bdc Add ocl's good features to track implementation. 
Additional notes with this commit:
1. Add cornerHarris_dxdy and cornerMinEigenVal_dxdy to get
the interim dx and dy output of Sobel operator;
2. Add minMax_buf to allow user to reuse buffers in minMax;
3. Fix an error when either min or max pointer fed into minMax is NULL;
4. Corner sorter temporarily uses C++ STL's quick sort. A parallel
 selection sort in OpneCL is contained in the implementation but disabled
due to poor performance at the moment.
5. Accuracy test for ocl gfft.
