V4l1 is no longer available in 2.6.38 kernel

Description
In the 2.6.38 kernel (used in Ubuntu Natty), the 'linux/videoinput.h' header file is no longer available. This breaks the compilation of 'opencv/modules/highui/src/cap_libv4l.cpp'.

A temporary patch which fixes the problem in Ubuntu is provided. It requires the installation of the 'libv4l-dev' package, which provides a replacement 'libv4l1-videodev.h' header.
