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:

The opencv element includes were full of duplicates and uneeded headers.
For example a few elements that stopped using gstcvopencvutils still
included that header file.
Some distributions store OpenCV files in /usr/share/opencv and some others
(and default when building from source) install them in
/usr/share/OpenCV. Support both to find cascade files.

Checking the vector is not empty and checking the vector size is greater
than zero are the same thing, this is a redundancy in the code. Only
checking the vector is not empty is sufficient, therefore removing the
other check.
Since the profile gchar depends on DEFAULT_FACE_PROFILE, it should never be
NULL. Furthermore CascadeClassifier accepts any input, even
an empty one, but if the profile fails to load it returns an empty cascade.
Check for this instead, and inform the user if there was an Error.
Check if profile is NULL before dereferencing it with new. Also, new will
never return NULL; if allocation fails, a std::bad_alloc exception will be
thrown instead. Remove check for a NULL return.

The cascade classifier changes its structure on new version of OpenCV.
The need to migrate to C++ to utilize the new load method of OpenCV which
allows to load the new classifiers.
