60731adea6 va: Avoid the array index overflow when filling 8x8 scaling list.
The VA API has not defined the scaling list entries for U/V planes
for the 4:4:4 stream. In fact, we do not meet the 4:4:4 format output
for H264 so far, and scaling list is not used frequently, so we just
print out some warning and ignore these scaling list values.

b6538e0560 va: Add and use common decode negotiate vmethod.
This vmethod can be used by decoders with the same VA decoder reopen logic:
same profile, chroma, width and height.

Also a new public method called gst_va_base_dec_set_output_state() with the
common GStreamer code for setting the output state, which is always called by
the negotiate vmethod.

In order to do this refactoring, new variables in vabasedec have to be populated
by the decoders:

* width and height define the resolution set in VA decoder. In the case of H264
  would be de coded_width and codec_height, or max_width and max_height in AV1.
* output_info is the downstream video info used for negotiation in
  gst_va_base_dec_set_output_state().
* input_state, from codec parent class shall be also held by vabasedec

4a8ecc2dba va: Add and use gst_va_base_dec_prepare_output_frame().
This helper will do downstream negotiation and later will
allocate the output frame.

H265 and AV1 decoders don't use this approach since their output
frame allocation is different.

f1a9728b30 va: Remove last_ret error handling in decoders.
It was used in the early development of the base classes. Now it
shouldn't be needed.

de5b76a922 va: Add and use gst_va_base_dec_process_output().
This function will copy the frame, if it's needed, and will apply buffer flags.

The function is used by all the decoders.

c8a0d706ca va: Add render node name in non-first devices.
There could be multi-GPU setups where the non-first has more
entrypoints than the first one, and the elements names are not
homogeneous, leading to pipeline building error.

This patch add the render node in the elements names when they belong
to the non-first device.

8c59ee29c2 vah264dec: Complete profiles in decoder.
Instead of specifying all the H.264 "supported" profiles in the global
hash table (used either by decoders and encoders), just complete them
in the decoder only, since the encoder doesn't support them.

c47255d148 va: basedec: Select format from template or negotiated caps.
Instead of using a hard-coded list of preferred formats according the
chroma type, now if now caps are pre-negotiated, from template caps
will choose the first format with the same chroma type. If
pre-negotiated, then it will choose the first format, with same chroma
type, from the first caps structure.

Also all the decoders will check if GST_VIDEO_FORMAT_UNKNOWN is
returned, failing the negotiation.

6434d69f8c codecs: Stop claiming constness for refcounted object
It's almost pointless and makes little sense as subclass might
want to modify refcount of the object or so. And all subclasses
are already casting them to non-const version as well.
In a general sense, we need to avoid passing refcounted object
with const qualifier.

4a4823b972 va: Delay decoders downstream negotiation.
Delay decoders downstream negotiation just before an output frame
needs to be allocated.

This is required, are least for H.264 and H.265 decoders, since
codec_data might trigger a new sequence before finishing upstream
negotiation, and sink pad caps need to set before setting source pad
caps, particularly to forward HDR fields. The other decoders are
changed too in order to keep the same structure among them.

97e3f88c20 va: Move common variable need_negotiation to GstBaseDec.
This is a common variable to all decoders, so it's sound to move it to
the base helper.

a2a3c81c85 va: Move back parent_object to each element.
Using GstBaseDec hack to access the parent_object of each element in
the element itself is a bit fragile. It would be better to keep its
own parent object as the usual global variable. It would make it
resistant to code changes.

The GstBaseDec macro to access the parent object now it's internal to
base decoder.

e322745763 codecs: h264decoder: Use GstFlowReturn everywhere
boolean return value is not sufficient for representing the reason
of error in most cases. For instance, any errors around new_sequence()
would mean negotiation error, not just *ERROR*.
And some subclasses will allocate buffer/memory/surface on new_picture()
but it could be failed because of expected error, likely flushing
