9bf1ae04cc vaapiupload: fix illegal write in ensure_image().
Fix ensure_image() to only zero-initialize the first line of each plane.
Properly initializing each plane to their full vertical resolution would
require to actually compute it based on the image format.

In particular, for NV12 images, the UV plane has half vertical resolution
vs. the Y plane. So using the full image height to initialize the UV plane
will obviously lead to a buffer overflow. Likewise for other YUV format.

Since ensure_image() is only a helper function to initialize something,
and not necessarily the whole thing, it is fine to initializ the first
line only. Besides, the target surface is not rendered either.

bd3aa01de5 build: fix compiling of local GstVideoDecoder and codecparsers.
Generated source files were missing a dependency on the complete set of
generated header files. e.g. gstvideodecoder.c requires gstvideoutils.h
to build and almost every codec parser source depends on parserutils.h.

ddaaa42020 h264: set {luma,chroma}_log2_weight_denom to 0 if no pred_weight_table().
Force luma_log2_weight_denom and chroma_log2_weight_denom to zero if
there is no pred_weight_table() that was parsed.

This is a workaround for the VA intel-driver on Ivy Bridge.

564ca5d221 mpeg2: fix decoding of sequence_end().
There shall be only one place to call decode_current_picture(), and this
is in the end_frame() hook. The EOS unit is processed after end_frame()
so this means we cannot have a valid picture to decode/output at this
point.

4499f39274 decoder: handle decode-only frames in raw API mode.

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.

41dcd82e2f vaapidecode: handle decode-only frames.
Decode-only frames may not have a valid surface proxy. So, simply discard
them gracefully, i.e. don't create meta data information. GstVideoDecoder
base class will properly handle this case and won't try to push any buffer
to downstream elements.

23c6053b94 wayland: fix frame_redraw callback.
The redraw callback needs to be attached to the surface prior to the
commit. Otherwise, the callback notifies the next surface repaint,
which is not the desired behaviour. i.e. we want to be notified for
the surface we have just filled.

Another isse was the redraw_pending was reset before the actual completion
of the frame redraw callback function, thus causing concurrency issues.
e.g. the callback could have been called again, but with a NULL buffer.

087bf30c23 wayland: fix display sharing.
When the Wayland display is shared, we still have to create our own local
shell and compositor objects, since they are not propagated from the cache.
Likewise, we also need to determine the display size or vaapisink would
fail to account for the display aspect ratio, and will try to create a 0x0
window.
