opencv, opencv-samples: add 2.4.2

Libav is easier to get right than gstreamer, so switch back. Also enable libv4l for better v4l(2) support

+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 .
