1eeea942de h265decoder: Fix a memory leak because of slice header.
The gst_h265_slice_hdr_free() should free the slice header just
parsed, not the priv->current_slice. Or, the memory leak will
happen because we do not free the slices in priv->nalu list.

02359dd251 h265decoder: Do not abort when failed to prepare ref pic set
Currently the element calls abort when failed to prepare reference
picture set. This can happent when the input stream is somehow
corrupted, like a rtsp strem with lost packets. Now it will only
return with GST_FLOW_ERROR instead of terminating whole process.

2ede4011bf codecs: Keep track of non-decoding-essential input state change
In theory, input caps can be updated anytime at non-keyframe or
sequence boundary, such as HDR10 metadata, framerate, aspect-ratio
or so. Those information update might not trigger ::new_sequence()
or subclass may ignore the changes.

By this commit, input state change will be tracked by baseclass
and subclass will be able to know the non-decoding-essential
update by checking the codec specific picture struct
on ::output_picture()

59e60203ba h265decoder: Reorganize debug printing
As of the MR
https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/2575
gst_h265_decoder_process_sps() is called per slice and it causes
noisy debug message print.
Reorganize related and the other debug printings at once.

8ec0dca73b codecs: h265: Make sure that sps is processed just before decoding
It may happens that bitstream doesn't provided SPS in decoding order
(like in VPSSPSPPS_A_MainConcept_1 conformance test file).
To be sure that the decoder got the correct SPS parameters process
SPS just before start decoding the frame.

8d40531f23 h265decoder: Improve robustness against malformed NAL packets
Use newly added gst_h265_parser_identify_and_split_nalu_hevc()
method to handle broken streams where packetized NAL unit
contain start code prefix in it.

It's obviously wrong stream but we know how to work around it
and even need to support such broken streams since
stateless decoder implementations are being a primary
decoder element.

ad136cb2c5 h265decoder: Fix for unhandled low-delay decoding case
Baseclass calls get_preferred_output_delay() in a chain of
sequence header parsing and then new_sequence() is called
with required DPB size (includes render-delay) information.
Thus latency query should happen before the sequence header
parsing for subclass to report required render-delay accordingly
via get_preferred_output_delay() method.
(e.g., zero delay in case of live pipeline)

This commit is to fix wrong liveness signalling in case of
upstream packetized format.

9d51cae7ee h264decoder,h265decoder: Do not hold codec_data buffer
... also do not need to extract it from caps.

Decoder uses codec_data only once per set_format() and
baseclass will extract codec_data buffer already.

3e49ff0ff5 h265decoder: Drain decoder on new_sequence()
Holding previously decoded but not outputted pictures even after
new_sequence is not a safe approach in various aspect.
However, we cannot drain out DPB on new_sequence() unconditionally,
because there is a case where decoder should drop decoded pictures
if NoOutputOfPriorPicsFlag is set.

To detect NoOutputOfPriorPicsFlag before the new_sequence() call,
this patch splits decoding process into two path, one for nal unit parsing
in order to detect NoOutputOfPriorPicsFlag and then each nal unit
will be decoded.

88437a9c9b codecs: Use GST_VIDEO_DECODER_ERROR() only for decoding error case
The GST_VIDEO_DECODER_ERROR() should be used only for robust/error-resilient
decoding purpose. Any other error codes such as not-negotiated or flushing
should be returned without modified for upstream to be able to handle
it immediately. (for example, application might want to try other
decoder element on not-negotiated)

5b405d1585 codecs: h265decoder: 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
