b4a695cd11 libs: video: split allocation query caos and pad caps
Since the allocation query caps contains memory size and the pad's caps
contains the display size, a video encoder or decoder might need to allocate
a different frame size than the size negotiated in the caps.

This patch splits this logic distinction for videodecoder and videoencoder.

The user if needs a different allocation caps, should set the allocation_caps
in the GstVideoCodecState before calling negotiate() vmethod. Otherwise the
allocation_caps will be the same as the caps set in the src pad.

7d35a07f1a Revert "videoencoder: Release video frame when ->handle return ERROR or DROPPED"
This reverts commit 63517d0ed3.

It was wrong ref counting wise and we decided to deprecated DROPPED

f5eebb27a2 {audio,video}{en,de}oder: Also copy POOL metas and make sure to copy over metas when creating subbuffers
POOL meta just means that this specific instance of the meta is related to a
pool, a copy should be made when reasonable and the flag should just not be
set in the copy.

87d6c265a8 video{en,de}coder: Call reset() before the start() vfunc
This makes sure that the element is in the same state before start() is called
the very first time and every future call after the element was used already.

Also it ensure that we always have a clean state before start(), cleaned the
same way in every case.

098b42f36b video{en,de}coder: Reset the codec after calling the stop() vfunc
The stop() vfunc might mess with some of our fields we have just
reset, which could cause memory leaks or invalid state taken over
to later.

Also the stop() vfunc, or anything called until it from another thread,
might want to be able to use the fields that were just resetted and
become confused because of that.

In the decoder we already had a workaround for things like this happening,
this workaround is not needed anymore.

7b428a8bcb videoencoder: Stop storing if we received EOS
This was never reset when going from PAUSED->READY and resulted
in encoders being not reusable after EOS. They just rejected any
buffer because they received EOS in their previous life.

The flag wasn't used anywhere except for rejecting buffers after
EOS, and this is now handled by GstPad directly.

79ef75888c videodec/enc: clear reconfigure flag if negotiate succeeds
So that it avoids to send an allocation query twice.
One from an early call to gst_video_encoder_negotiate from a
subclass, then one from gst_video_encoder_allocate_output_frame.
Which means that previously gst_video_encoder_negotiate was not
clearing the GST_PAD_FLAG_NEED_RECONFIGURE even on success.
