[MPlayer-dev-eng] [PATCH] MPlayer-CVS with V4L compile when V4L2 installed

this small patch allows to compile the file libmpdemux/tvi_v4l.c properly, 
when the Linux is patched with the V4L2 patch, which automatically 
includes <linux/videodev2.h> when you include <linux/videodev.h>.
It is necessary then to prevent <linux/time.h> from including (by defining 
the _LINUX_TIME_H macro) in order to resolve some collisions and it is 
also necessary to prevent the defining of "struct v4l2_capability" and 
"VIDIOC_QUERYCAP" in libmpdemux/tvi_v4l.c, when they are allready defined 
in the <linux/videodev2.h>.
