et61x251 doesn't use vidioc_ioctl2. As the API is changing to use
a common version for all drivers, we need to expliticly fix this
driver.

The et61x251 driver claims a whole list of usb id's, but it only has
one sensor "module" which does sensor detection based on usb id and that
only supports devices with the 102c:6251 usb id. Remove the usb-ids for
other devices as for those the driver will fail with an unable to determine
sensor type message anyways.

- Make the driver depend on V4L2 only (KConfig)
- Better and safe locking mechanism of the device structure on open(),
  close() and disconnect()
- Use kref for handling device deallocation
- Generic cleanups

Because of historic reasons, there are two separate directories with
V4L stuff. Most drivers are located at driver/media/video. However, some
code for USB Webcams were inserted under drivers/usb/media.

This makes difficult for module authors to know were things should be.
Also, makes Kconfig menu confusing for normal users.

This patch moves all V4L content under drivers/usb/media to
drivers/media/video, and fixes Kconfig/Makefile entries.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
