We will need this helper inside libavcodec in the future, so move it
there, leaving behind an #include to the raw source file in its old
location in libvfilter. This approach is inspired by the handling of
vulkan.c, and avoids us needing to expose any of it publicly (or
semi-publicly) in e.g. libavutil, thus avoiding any ABI headaches.
It's debatable whether the actual code belongs in libavcodec or
libavfilter, but I decided to put it into libavcodec because it
conceptually deals with encoding and decoding ICC profiles, and will be
used to decode embedded ICC profiles in image files.

GPU hang is one of the most typical errors on Intel GPUs in
case something goes wrong. It's important to recognize it
explicitly for easier bugs triage. Also, this error code
can be used to trigger GPU recovery path in self-written
applications.
There were 2 other statuses which MediaSDK can ppotentially return,
MFX_ERR_NONE_PARTIAL_OUTPUT and MFX_ERR_REALLOC_SURFACE. Adding
them as well.
v2: move MFX_ERR_NONE_PARTIAL_OUTPUT next to MFX_WRN_* (Haihao)

The streamcopy initialization code briefly needs an AVCodecContext to
apply AVOptions to. Allocate a temporary codec context, do not use the
encoding one.
Instead replace VP56mv by new and identical structures VP8mv and VP9mv.
Also replace VP56Frame by VP8FrameType in vp8.h and use that
in VP8 code. Also remove VP56_FRAME_GOLDEN2, as this has only
been used by VP8, and use VP8_FRAME_ALTREF as replacement for
its usage in VP8 as this is more in line with VP8 verbiage.
This allows to remove all inclusions of vp56.h from everything
that is not VP5/6. This also removes implicit inclusions
of hpeldsp.h, h264chroma.h, vp3dsp.h and vp56dsp.h from all VP8/9
files.
(This also fixes a build issue: If one compiles with -O0 and disables
everything except the VP8-VAAPI encoder, the file containing
ff_vpx_norm_shift is not compiled, yet this is used implicitly
by vp56_rac_gets_nn() which is defined in vp56.h; it is unused
by the VP8-VAAPI encoder and declared as av_unused, yet with -O0
unused noninline functions are not optimized away, leading to
linking failures. With this patch, said function is not included
in vaapi_encode_vp8.c any more.)

suppose
a. You have 3 frames, 0, 1, 4096.
b. The ltMask is 0xfff and use_msb is 0.
c. The 0, 1 are lt refs for 4096.
d. you are decoding frame 4096, and get the 0 frame.
Since 4096 & ltMask is 0 too, even you want get 0, find_ref_idx may give you 4096.
add_candidate_ref will report an error for this

We will generate a new frame for a missed reference. The frame can only
be used for reference. We assign an invalid decode sequence to it, so
it will not be involved in any dpb process.

It used to be allocated separately, so that the pointer to it
is copied to all HEVCContexts, so that all slice-threads
use the same. This is completely unnecessary now that there
is only one HEVCContext any more. There is just one minor
complication left: The slice-threads only get a pointer to
const HEVCContext, but they need to modify the common CABAC
state. Fix this by adding a pointer to the common CABAC state
to HEVCLocalContext and document why it exists.

Actually, ff_slice_thread_allocz_entries() always already
allocates zeroed entries, so ff_reset_entries() was already
unnecessary. Make this more clear by renaming it to
ff_slice_thread_allocz_entries().

The HEVC decoder has both HEVCContext and HEVCLocalContext
structures. The latter is supposed to be the structure
containing the per-slicethread state.
Yet up until now that is not how it is handled in practice:
Each HEVCLocalContext has a unique HEVCContext allocated for it
and each of these coincides except in exactly one field: The
corresponding HEVCLocalContext. This makes it possible to pass
the HEVCContext everywhere where logically a HEVCLocalContext
should be used. And up until recently, this is how it has been done.
Yet the preceding patches changed this, making it possible
to avoid allocating redundant HEVCContexts.

Right now the code passes a list of ints whose entry #i
is just i as opaque parameter to hls_decode_entry_wpp
via execute2; said list is even constantly allocated and freed.
This commit stops doing so and instead passes the list of
HEVCLocalContext* instead, so that the main HEVCContext
can be avoided in accessing the HEVCLocalContext.

It also constifies what can be constified in order to make
the nonconst stuff stand out more.
