3cc7b26961 libs: use GstVaapiMiniObject for video decoders.
Port GstVaapiDecoder and GstVaapiDecoder{MPEG2,MPEG4,JPEG,H264,VC1} to
GstVaapiMiniObject. Add gst_vaapi_decoder_set_codec_state_changed_func()
helper function to let the user add a callback to a function triggered
whenever the codec state (e.g. caps) changes.

c43a2d497a decoder: add gst_vaapi_decoder_get_frame_with_timeout().
Add gst_vaapi_decoder_get_frame_with_timeout() helper function that will
wait for a frame to be decoded, until the specified timeout in microseconds,
prior to returning to the caller.

This is a fix to performance regression from 851cc0, whereby the vaapidecode
loop executed on the srcpad task was called to often, thus starving all CPU
resources.

a24e216466 decoder: rename GstVaapiDecoderFrame to GstVaapiParserFrame.
Rename GstVaapiDecoderFrame to GstVaapiParserFrame because this data
structure was only useful to parsing and a proper GstvaapiDecoderFrame
instance will be created instead.

4009430bec decoder: sanitize codec-data decoding.
Add a new GstVaapiDecoder::decode_codec_data() hook to actually decode
codec-data in the decoder sub-class. Provide a common shared helper
function to do the actual work and delegating further to the sub-class.

2305b0db46 decoder: allow frames to be dropped.
If the decoder was not able to decode a frame because insufficient
information was available, e.g. missing sequence or picture header,
then allow the frame to be gracefully dropped without generating
any error.

It is also possible that a frame is not meant to be displayed but
only used as a reference, so dropping that frame is also a valid
operation since GstVideoDecoder base class has extra references to
that GstVideoCodecFrame that needs to be released.

e4e3a58bc0 decoder: fix check for end-of-stream in raw API mode.
Make sure to immediately return GST_VAAPI_DECODER_STATUS_END_OF_STREAM
if the end-of-stream was already reached at the previous iteration.

4fd99cc989 decoder: use an array of units instead of a single-linked list.
Use a GArray to hold decoder units in a frame, instead of a single-linked
list. This makes 'append' calls faster, but not that much. At least, this
makes things clearer.

8c2d9bcd24 decoder: maintain decoded frames as GstVideoCodecFrame objects.
Maintain decoded surfaces as GstVideoCodecFrame objects instead of
GstVaapiSurfaceProxy objects. The latter will tend to be reduced to
the strict minimum: a context and a surface.

e7e5c74a6e decoder: use GstVideoCodecState.
Use standard GstVideoCodecState throughout GstVaapiDecoder and expose
it with a new gst_vaapi_decoder_get_codec_state() function. This makes
it possible to drop picture size (width, height) information, framerate
(fps_n, fps_d) information, pixel aspect ratio (par_n, par_d) information,
and interlace mode (is_interlaced field).

This is a new API with backwards compatibility maintained. In particular,
gst_vaapi_decoder_get_caps() is still available.

66cc8754fc decoder: add new GstVaapiDecoder API.
Split decoding process into two steps: (i) parse incoming bitstreams
into simple decoder-units until the frame or field is complete; and
(ii) decode the whole frame or field at once.

This is an ABI change.

e5d12e8853 decoder: rework the internal VA objects API.
The new API simplifies a lot reference counting and makes it more
flexible for future additions/changes. The GstVaapiCodecInfo is
also gone. Rather, new helper macros are provided to allocate
picture, slice and quantization matrix parameter buffers.

3e1d235c1a decoder: fix possible leak of VA surfaces.
Under some circumstances, we could have leaked a surface, thus not
releasing it to the pool of available surfaces in the VA context.
The strategy is now to use a proxy earlier and automatically ref/unref
whenever necessary. In particular, during the lifetime needed for FFmpeg.
