89096dde38 h264decoder: Update output frame duration when second field frame is discarded 
In case of an interlaced stream, if each field picture belongs to
different GstVideoCodecFrame, updates output frame's duration
based on discarded second field picture's timestamp information.

And change lengths and indices from guint to gsize for a more correct type.

Also deprecate GstQueueArray and implement it in terms of GstVecDeque.

e353fe8fcc h264decoder: Handle malformed avc/avc3 packets 
Packetized stream format should not contain start-code prefix
in bitstream and each [nal-length-byte, nal-byte] unit should consist of
single nal unit. But there are malformed streams in the world.
Use newly added gst_h264_parser_identify_and_split_nalu_avc()
method to identify each nal unit.

48a0c01570 h264decoder: Update latency dynamically 
The actual number of reorder frames is unknown
unless frame reordering is disabled
(e.g., POC type 2 or constrained-* profiles).
Also derived maximum DPB size or max_num_reorder_frames in VUI
is not the upper bound of output delay.

57e0bdb356 h264decoder: use last_output_poc from DPB 
It seems that `last_output_poc` in `h264decoder` class is a left over of commit
5527cc4a2e.

This patch removes it but keeps the log message by fetching the `h264picture`'s
`last_output_pic`.

13b36cd4e3 h264decoder: fail early if no input caps have been provided 
The h264decoder class does not implement the ->parse() virtual function,
and we always need to add the h264parse element before it. So we should
set_needs_format of the decoder to TRUE, then if no parse before it, it
can fail with a "not-negotiated" error early, rather than go on and
generate unexpected error.

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()

8ec4452d67 h264decoder: 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.

104ae1b2e6 codecs: h264: Save the field_pic_flag 
This flag is set when the stream is interlaced and the specific
slice is made of single parity fields rather the paired at the
macroblock layer. This is rarely needed in late decoding process
but the Rockchip RKVDEC HW interface requires it, hence needs to
be passed through V4L2 Stateless interface.

0345188aaa codecs: h264dec: Calculate the latency by its bump mode. 
The current latency calculation just uses the num_reorder_frames,
which is not very precise. We should consider the bump mode of the
DPB, the faster it bumps, the lower latency we will have.

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)

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
