Advertise to upstream that vaapipostproc can handle
crop meta.
When used in conjunction with videocrop plugin, the
videocrop plugin will only do in-place transform on the
crop meta when vaapipostproc advertises the ability to
handle it. This allows vaapipostproc to apply the crop
meta on the output buffer using vaapi acceleration.
Without this advertisement, the videocrop plugin will
crop the output buffer directly via software methods,
which is not what we desire.
vaapipostproc will not apply the crop meta if downstream
advertises crop meta handling; vaapipostproc will just
forward the crop meta to downstream. If crop meta is
not advertised by downstream, then vaapipostproc will
apply the crop meta.
Examples:
1. vaapipostproc will forward crop meta to vaapisink
gst-launch-1.0 videotestsrc \
! videocrop left=10 \
! vaapipostproc \
! vaapisink
2. vaapipostproc will do the cropping
gst-launch-1.0 videotestsrc \
! videocrop left=10 \
! vaapipostproc \
! identity drop-allocation=1 \
! vaapisink
We no longer need this obsolete set_property function now after
switch to standard gobject's property manner.
Also delete the old encoder's property enum in the header file.
The encoder is a true gstobject now and all the properties are using
gobject's properties mechanism. Add help functions to handle the properties
between encode and encoder class.
The basic idea is mapping the same property between encoder and encode. All
the encoder's properties will have the same name, the same type in encode.
The set/get property function just forward the property setting/getting to
the encoder using the same property name and value. Because the encoder is
created on needed, we need to cache the property setting in encode.
G_PARAM_CONSTRUCT make all properties init correctly, we do not
need to init the properties manually.
G_PARAM_FLAG_VAAPI_ENCODER_EXPOSURE is a vaapi encoder specific
flag, means need to expose the property to according encode class.
Install properties for h264 encoder fei class. Also set the new get/set
property functions for gobject class. Still use the old properties
way now and this new feature will be enabled later.

Replace all gstvaapiobject in vaapi encoders with standard gstobject.
Let the gstobject common logic to handle all the init and finalize
works. But the property install/set/get still use the old way, need
to be improved later.
While ensuring the allowed sink pad caps, the filter attributes set
the frame size restriction, but it is not ensured, at that moment,
that the filter is already instantiaded.
In order to silence the glib logs, this patch add only calls
gst_vaapi_filter_append_caps() if the filter is instantiated.
The context overlay was an optimization to apply a video composition
to all the surfaces bound to a context.
But since commit 18031dc6 this optimization was disabled, so it is
better just get rid of it.
In commit 18031dc6 surface's parent context is not assigned because of
circular references. Since then (2013), there's has no issue with
subpictures attached to a context, the current only users of this API.
This patch cleans up all of related code with the unused surface's
parent context.
