The vivi.current_norm field is not initialized in vivi.c, so a
VIDIOC_G_STD ioctl without a prior call to VIDIOC_S_STD gives
unpredictable results. mplayer does exactly this.

when checking the -Wextra signedness warnings issued by gcc 4.1
I came across this one:
drivers/media/video/vivi.c:1001: warning: comparison of unsigned expression < 0 is always false
Since videobuf_reqbufs() returns negative values on errors the current
code does no real error checking since gcc removes the comparison.
This patch fixes this issue by making ret a normal, signed integer.

Removed usage of HAVE_V4L1
Including videodev.h will just include videodev2.h if V4L1 is not supported
V4L1 code at core drivers will honor CONFIG_V4L1_COMPAT stuff

Several common handling codes were removed. Maybe even more
stuff may be handled at common infrastructure.

V4L1 API is depreciated and should be removed soon from kernel. This patch
adds two new options, one to disable V4L1 drivers, and another to disable
V4L1 compat module. This way, it would be easy to check what still depends
on V4L1 stuff, allowing also to test if app works fine with V4L2 only support.

The Virtual Video Device Driver (aka vivi) is a device that
can be used to:
1) test core v4l functionalities;
2) be a prototype for newer development.
Vivi were developed using the best practices for v4l driver.
When loaded, it provides a video device that generates a
standard color bar, with a timestamp placed at top left corner.
