The CTA-861 standards have been updated to refer to opRGB instead
of AdobeRGB. The official standard is in fact named opRGB, so
switch to that.

The two old defines referring to ADOBERGB in the public API are
put under #ifndef _KERNEL and a comment mentions that they are
deprecated.

This keeps us in sync with the linux header.

Avoid __u8, __u16, __u32, __u64, __s32, __s64, and __le32 and use standard

Sync with Linux kernel version 4.10-rc6.

The licence of v4l2-common.h was changed to both GPLv2 and BSD
(https://git.linuxtv.org/media_tree.git/commit/?id=80100fd9ebb9f2414892a1178d26a4253e6c0bcf),

v4l2-controls.h, and videodev2.h of the Linux kernel.

Include sys/ioccom.h since _IO* is used.

Based on the number and type of other system headers which pull in ioccom.h, and
the fact that videoio.h isn't involved in any massive chain of includes in the
kernel, I think it's reasonable and makes porting simpler. -- sthen@

Sync V4L2 header file with upstream (i.e., recent Linux kernel) headers.

This syncs our videoio.h with upstream videodev2.h and inlines their
v4l2-controls.h (which was split off from videodev2.h). Another header,
v4l2-common.h, is currently not imported as it is GPL2 licensed.

There will be a second commit just addressing whitespace and formatting. The
current version has only real changes whereas the second commit will bring
videoio.h in line with videodev2.h formatting so that potential syncs in the
future are easier to implement.

Initial import for uvideo(4) and video(4):

uvideo(4) is a driver for USB video device class devices including webcams,

video(4) is a device-independent layer that implements the V4L2 (Video for Linux Two)

These drivers are *really* work in progress so don't even try to use them just yet,
