Simply produce the result into the output image provided by the base
class. This avoid useless copy. This also removes unchecked buffer map
and ensure that GstVideoMeta is respected (for stride mostly).

a) Use get_pkgconfig_variable() to get the opencv prefix
b) Place an upper limit on the opencv version
c) Ensure that headers are available
(b) and (c) just copy what the configure.ac checks do.

Use namespace only after it was actually defined by a header.
gstfacedetect.cpp:79:17: error: using directive refers to implicitly-defined namespace 'std' [-Werror]
using namespace std;
^
- add using namespace std; for std::vector
- use the cpp header imgproc.hpp file for the cv::ellipse function instead of
the C header
- Mat no longer takes IplImage in it's constructors, use the cvarrtomat()
function instead.
Fixes a couple of build errors:

Add namespace bgsegm, replacement functions and Template class for new
OpenCV versions because these functions have been removed. cvarrToMat() is
added because it is compatible with all versions of OpenCV and the use of
class Mat constructor is eliminated, it is also deprecated in 3.X versions.
Use the namespace cv because some functions are called many times.
This patch keeps compatibility with 2.4
https://bugzilla.gnome.org/show_bug.cgi?id=760473
imgproc_c.h is added because CvFont struct needs it in any 3.x version.
We use this structure in GstOpencvTextOverlay. This keeps compatibility
with 2.4.

Some members of MotionCells were not being initialized in the constructor.
Protect from potential garbage memory usage by fully initializing it.
Moving m_frameSize out of the class because it is only used in
performDetectionMotionCells().

cvPyrSegmentation() has been deprecated in OpenCV 3.0, and there isn't any

Remove calls to gst_pad_has_current_caps() which then go on to call
gst_pad_get_current_caps() as the caps can go to NULL in between. Instead just
use gst_pad_get_current_caps() and check for NULL.

Add a "mask" property that sets whether the edges by cvLaplace should be
used as a mask on the original input or not. The same way the original
image is copied to the edges in edgedetect.

cvCvtPixToPlane() has been deprecated in OpenCV 3.0, and cvSplit() is the
suggested replacement. Since cvSplit() is available in OpenCV 2.4, it is
safe and cautious to update the function usage before it becomes an issue.
cvlaplace was also affected by the silent change in OpenCV API, same as
cvsobel. It hasn't been working for a while. It would return a plain black
image. This commit updates the usage of cvLaplace by using cvCvtColor to
create the grayscale intermediate image to process. This also means there
is no need anymore to use GstBaseTransform's transform_caps, since the pads
are RGB.

After commit 64080e632, configure checks for all the header files that
should be available in OpenCV 2.3 and later. If any of these files isn't
there the OpenCV elements won't be part of the build.
No need to recheck for opencv2/legacy/legacy.hpp again in
gstpyramidsegment.h. Minimum supported OpenCV version must have this header
and configure already checks for it. Removing check.
Run the transform function of pyramidsegment in place, reusing the image
data as both source and destination in cvPyrSegmentation. This avoids
copying the image back and forth and the extra memory.
No need to attempt splitting the RGB string in 255 tokens
if we only expect 3.
Left max_tokens at 4 to preserve the current logic (which
allows for extra stuff at the end) and added a warning on
parsing failure instead of silently discarding the value.
