Nicolas Dufresne 2696bcd9e2 vp8decoder: Drain the output queue on EOS/finish 
The finish() virtual method was flushing the queue, instead push the
remaining buffers. It is not required to reset in finish() unlike
drain(). This a regression causing last frame to always be lost.

Nicolas Dufresne e5e2b6a652 v4l2slvp8dec: Only ask for output delay once per negotiation 
While it's technically possible to change it per frame, asking for
that every frame is not very useful. This mimic H264 decoder better.

Daniel Almeida 82c0005793 codecs: gstvp8decoder: add support for render delay 
Some decoding APIs support delayed output for performance reasons.
One example would be to request decoding for multiple frames and
then query for the oldest frame in the output queue.

This also increases throughput for transcoding and improves seek
performance when supported by the underlying backend.

Introduce support in the vp8 base class, so that backends that
support render delays can actually implement it.

He Junyan 6b3ff669ee codecs: vp8decoder: handle the show_frame check in base class. 
Move the show_frame check from sub class to vp8 decoder's base class.
Calling the sub class' output_picture() function only when the frame
is displayed and marking the other automatically as decode only.

This is done to avoid logic and code repetition in subclasses.

Seungha Yang deaa29bd96 codecs: vp8decoder: Sync up with h264decoder implementation 
Pass GstVideoCodecFrame with GstVp8Picture to new_picture() and
output_picture() methods for subclass to be able to reference
it directly.

Seungha Yang a89b819191 codecs: Add new baseclass for VP8 decoder 
This implemenation is similar to VP9 but much simpler than it.
