v4l plugins: add open/close signals v4l2 plugins: add open/close signals move source format enumeration from v4l2elem...
Original commit message from CVS: v4l plugins: * add open/close signals v4l2 plugins: * add open/close signals * move source format enumeration from v4l2element to v4l2src * adapt to the final v4l2 API in kernel 2.5 (patches for 2.4 on http://bytesex.org/patches) * small tweaks
