01051e7dfd msdkdec: don't set unknown picture struct to progressive for vc1
MFXVideoDECODE_DecodeHeader only parses the sequence layer for VC1, so
the structure is unknown for a stream with interlace flag set in the
sequence layer. If forcing the struct to progressive in this plugin,
MediaSDK will fail to decode such streams.

a751b33072 msdkdec: force the alignment of width/height to 16 for vp8/vp9
MSDK library requires 16 alignment for vp8/vp9, otherwise a pipeline
for vp8/vp9 decoding might fail.

example pipeline:
gst-launch-1.0 filesrc location=vp8_1280x720.webm ! matroskademux ! \
msdkvp8dec ! fakesink

edc0edc960 msdkvp9dec: use separate src caps
We will add more formats in the src caps of msdkvp9dec, so let
msdkvp9dec uses separate src caps. Note it doesn't change any
capability

409d4ff30e msdkdec: move output-order out of decode bass class.
Since output-order is a deprecated attribute, move it out of decode
bass class and configure it in each sub decoder class who need it.

1e95c03c7d msdk: dec: Add dynamic-configuration change support
The patch adds a serios of changes to support dynamic resolution
change and efficient utilization of resources.
Major changes:

-- Use MSDK's apis to retrieve the headers instead of only relying
on upsteram notification. For eg: avc decoder requires SEI header
information for dpb count calculation which we don't get from caps.

-- For all codecs other than VP9, we force the reset of decoder
if resoultion changes to fit with gstreamer flow. VP9 enfource
the hard reset only if the new resolution is bigger.

-- delay the src caps setting till msdk api's invokation in
handle_frame to avoid caching multiple configuration values

-- ensure pool negotiation is based on decoder's allocation_caps.

--dynamic resoluttion change use an explicit allocation_query
to reclaim the buffers before closing the decoder (thanks to v4l2dec)

--In case if we don't get upstream notification of res change (for eg,
this can can happen for vp9 frames with ivfheader where ivfparse
is not able to notify the dynamic changes), we handle the the case
based on MFX_ERR_INCOMPATIBLE_VIDEO_PARAM which is the return value
of MFXVideoDECODE_DecodeFrameAsync

-- calculate the minimum surfaces to be preallocated based on
msdk suggestion, downstream requirement, async depth and scratch surface
count for smooth display.
