The removed code set all the reference frames to the current frame it is a key
one, but later, all the reference frames were rewritten with the decoded picture
buffers or VA_INVALID_SURFACE if they were not available.
Basically, all this time the first reference frame assignment has been ignored,
and it's not described by the spec, and this patch removes that code.

If display size is smaller than current frame size, then the crop size
will be set as display size, which either crashes the pipeline or the
output MD5 does not match. Rather it should use the actual decoded size.
This patch removes the cropping set. For rendering we can use aspect
ratio to set display size.

The decoder's surface chroma type should depend on the bit depth
of VP9's parser. For 10bits VP9 stream, we need to use P10LE kind
10 bits surface as the decoder result.
Fixes#155
Clarify that vaapi context resets are never needed for vp9, but
that ensure_context() needs called when the size increases so that
new surfaces can be allocated.

The subsampling_x, subsampling_y, bit_depth, color_space and color_range
fileds are moved from GstVp9FrameHdr to the global GstVp9Parser structure.
These fields are only present in keyframe or intra-only frame, no need to
duplicate them for inter-frames.

As gst-indent generated ugly code in these cases, this patch changes the used
idiomatic into other one.
No functional changes were introduced.

We always set GST_VAAPI_PICTURE_FLAG_SKIPPED for DECODE_ONLY frames and the
gstvaapidecoder base calss is reponsible for handling those frames later on.
No need for explicit verification of frame header's show_frame in order to
do picture outputing.
Set crop rectange if:
There is display_width and display_height which is different from actual width/height
or
The changed resolution is less than the actual configured dimension of surfaces
Unlike other decoders, vp9 decoder doesn't need to reset the
whole context and surfaces for each resolution change. Context
reset only needed if resolution of any frame is greater than
what actullay configured. There are streams where a bigger
resolution set in ivf header or webm header but actual resolution
of all frames are less. Also it is possible to have inter-prediction
between these multi resolution frames.
clang complains about a couple variables and one label which were not
used. This patch removes them.
