[meta-oe] opencv: import from oe-classic and upgrade to 2.3.1

[Connor Abbott <cwabbott0@gmail.com>]

OpenCV <= 2.2 won't compile on oe-core due to the lack of v4l1 headers, and therefore wasn't included in this patch. Also, the support for newer cv2-style python bindings is a bit hacked up at the moment due to the way OpenCV detects the Python version and Numpy headers (see 0001-Fix-CMakeLists.txt-numpy-detection.patch). In particular, it requires the native & target python to be the same version and have similar site-packages directories, which is true at least for now in OE.

+Subject: [PATCH] Fix CMakeLists.txt numpy detection
+
+Right now, the code opencv uses to detect where the numpy include files are doesn't work with cross-compiling because it uses the native python to determine the environment. To make this a little better, allow the user to explictly specify the path using -DPYTHON_NUMPY_INCLUDE_DIRS=path/to/numpy/include/dir .
