[PATCH v4 00/13] Stateless H.264 de-staging

Seems we are converging, as this iteration is really small.

Just like v3, this iteration (plus a patch for VP8 VP8_FRAME_HEADER initialization,
which I'll send shortly) passes v4l2-compliance with no failures.

As an additional test, Fluendo's JVT-AVC_V1 conformance test [1] passes with
score 72/135, for the Hantro driver on i.MX8MQ (Hantro G1 VPU).
Considering the Hantro driver only supports 4:2:0 and 4:0:0, this score
looks quite good.

Thanks,

v4:
* Minor documentation fixes.
* Remove media/h264-ctrls.h, which was missing before.
* Thanks to feedback from Jernej, std_validation_compound
is now more complete, initializing non-present syntax elements.
v3:
* Dropped level control from Cedrus, as agreed.
* Add support for H264 stateless controls in std_log and std_validate_compound.
* Added a ctrl debug error message, to help debug validation issues.
* Style minor fixes as requested by Hans.
v2:
* Split destage changes in several patches so it's easier to review.
* Added missing changes to drivers/media/v4l2-core/v4l2-ctrls.c.
* Renamed V4L2_CID_CODEC_CX2341X_ and V4L2_CID_MPEG_MFC51_
* Moved the compatibility macros for MPEG to the end of the header.
