GstVaapiMiniObject and GstVaapiObject are deprecated.
This is the first step to remove them by porting GstVaapiCodedBuffer
as a GstMiniBuffer descendant.

An unsigned value can never be negative, so this test will always
evaluate the same way.

`info_to_pak` variable in gst_vaapi_encoder_h264_fei_encode() is
declared in the stack, but it is free in
gst_vaapi_feienc_h264_encode() as if declared on the heap.
This patch initializes the structure and removes the free.
A non-heap pointer is placed on the free list, likely causing a crash
later.
In gst_vaapi_encoder_h264_fei_encode: Free of an address-of
expression, which can never be heap allocated.
This patch makes use of GST_PARAM_USER_SHIFT to define the internal
param in encoders to decide which parameters to expose. Thus
gstreamer-vaapi will not interfere with any change in GStreamer in the
future.
Also, the internal symbol was change to
GST_VAAPI_PARAM_ENCODER_EXPOSURE to keep the namespacing.
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 fei encoder 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.
Increased max values of periodic key frame for h26x codecs.
This allow more fine tunning of encoder that in certian scenario
want higher periodic key frame.
For example: it doesn't want a key frame each 10 seconds but
each 120 seconds.

Adding FEI encoder to core lib.
The code is splitted into three session:
1: gstvaapiencoder_h264_fei.{h,c}
This is the replica of gstvaapiencoder_h264.{c,h} but with FEI.
All the modes ENC, PAK and ENC_PAK are running based
the code in these files.
2: gstvaapifeienc_h264.{h,c}
Abstract implementation intended for ENC (only VME) operation.
3: gstvaapifeipak_h264.{h,c}
Abstrct implementation intended for PAK (only the PAK module)
Right now ENC_PAK, ENC and PAK are running based on code
in gstvaapiencoder_h264_fei.{h,c}. The abstract implementations
in gstvaapifeienc_h264.{h,c} and gstvaapifeipak_h264.{h,c} are
needed if user request for ENC+PAK mode operation.
ENC+PAK: Here we need to invoke two sequence of
vaBeginPicture/vaRenderPicutre/vaEndPicture for each frame,
first for the ENC only and the second for PAK only.
Each mode associated with separate context ,but same pool of surfaces are
shared between the modes.
This is more useful once we have custom BRC algorithms.
