Add a debug message for control validation (validate_new)
failures. This is useful to debug issues with ioctls such
as VIDIOC_TRY_EXT_CTRLS and VIDIOC_S_EXT_CTRLS.

The Rockchip Video Decoder used in RK3399 supports H.264 profiles from
Baseline to High 4:2:2 up to Level 5.1, except for the Extended profile.
Expose the V4L2_CID_MPEG_VIDEO_H264_PROFILE and the
V4L2_CID_MPEG_VIDEO_H264_LEVEL control, so that userspace can query the
driver for the list of supported profiles and level.
For now, we don't expose 4:2:2 since the driver doesn't
implement the required support.

For historical reasons, stateful codec controls are named
as {}_MPEG_{}. While we can't at this point sanely
change all control IDs (such as V4L2_CID_MPEG_VIDEO_VP8_FRAME_HEADER),
we can least change the more meaningful macros such as classes
macros.

Avoid including h264-ctrls.h, vp8-ctrls.h, etc,
and instead just include v4l2-ctrls.h which does the right
thing.
This is in preparation for moving the stateless controls
out of staging, which will mean removing some of these headers.

When V4L2_CTRL_TYPE_H264_PRED_WEIGHTS was added, adding a replace
symbol directive in videodev2.h.rst.exceptions was missed.
Now that the control type is destaged, it's important to fix this.

Move the H264 stateless control types out of staging,
and re-number them to avoid any confusion.

For now, only print the type of the control. In the future,
we might want to be able to print the values of all
the stateless codec controls currently set in the control handler,
which should be useful for debugging reasons.

The H264 stateless controls is ready to be part
of the stable uAPI.
Re-number the control IDs, move them to the newly
created stateless control class, and updates all
the drivers accordingly.

The H.264 stateless 'uAPI' was staging and marked explicitly in the V4L2
specification that it will change and is unstable. And it has in fact
changed several times.
By renumbering these control IDs it in fact avoids any possible confusion
if someone based their work on the unstable uAPI.
Note that these control IDs were *never* exported as a public API,
they were only defined in kernel-local headers (h264-ctrls.h). So
applications that wanted to use this staging API had to manually copy
that header.
In other words, there never was a public API for this since the H.264
header was never exported.

Hans

Now that we've destaged the H264 stateless codec controls,
and with all the pieces in place, update the documentation
and move it to its own section.

+Stateless Codec Control Reference
+*********************************
+
+The Stateless Codec control class is intended to support
+stateless decoder and encoders (i.e. hardware accelerators).
+
+These drivers are typically supported by the :ref:`stateless_decoder`,
+and deal with parsed pixel formats such as V4L2_PIX_FMT_H264_SLICE.

+ Semantics". For further documentation, refer to the above
+ specification, unless there is an explicit comment stating
