08b4aaa7fa libs: decoder: vp9: avoid reference rewriting
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.

958ea067cb libs: dec: vp9: do not use display size as decoded size
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.

Fixes #175

a4e2db4c0b libs: decoder: vp9: support 422/444 8bit/10bit chroma type.
According to the vp9 sepc, profile 1/3 support 422/440/444 chroma
type, so we need to add subsampling_x&subsampling_y to fix it.

Here is the relationship between chroma type and profile and
subsampling_x&subsampling_y according to vp9 spec:
------------------------------------------
Profile | Bit depth | Chroma subsampling |
------------------------------------------
 0      | 8         | 420                |
------------------------------------------
 1      | 8         | 422,440,444        |
------------------------------------------
 2      | 10, 12    | 420                |
------------------------------------------
 3      | 10, 12    | 422,440,444        |
------------------------------------------

-----------------------------------------------
Subsampling_x | Subsampling_y | Chroma format |
-----------------------------------------------
 0            | 0             | 444           |
-----------------------------------------------
 0            | 1             | 440           |
-----------------------------------------------
 1            | 0             | 422           |
-----------------------------------------------
 1            | 1             | 420           |

9c1f3ad172 lib: decoder: vp9: Set chroma_type by VP9 bit_depth
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.

80c3bfe448 decoder: vp9: Align with the ABI changes in vp9 codecparser
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.

a48eebefd6 decoder: vp9: Fix the context and surface pool reset for multi resolution video
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.
