025f8b9129 vc1parse: implement asf to *-frame-layer stream-format
This commit add an helper to convert a frame to frame-layer format and
use it to implement these two stream-format conversion:
- asf --> sequence-layer-frame-layer
- asf --> frame-layer

In simple/main profile, we basically have a raw frame, so building a
frame layer isn't too complicated. But in advanced profile, the first
frame-layer should contain sequence-header, entrypoint, and frame and
each keyframe should contain entrypoint, so we have to handle these
carefully.

f2c5900c6d vc1parse: add some simple stream-format conversion
It add the support of following stream-format conversion:
- bdu --> sequence-layer-bdu
- bdu-frame --> sequence-layer-bdu-frame
- frame-layer --> sequence-layer-frame-layer

For these conversion, the only requirements is to push a sequence-layer
buffer prior to data.

89455b7106 vc1parse: select caps according to wmv format at negotiation
Some VC1 decoder can have different caps according to wmv format, ie
WMV3 or WVC1.
So instead of keeping the first available caps, we interserct with
current WMV format.

52ac7cf27a videoparser: comment unused GST_BASE_PARSE_FRAME_FLAG_PARSING
GST_BASE_PARSE_FRAME_FLAG_PARSING value is wrong, and the same flag is
not being used presently. Hence changing the value and commenting it out.
This needs to be included in baseparse.h later on

d03f5499bd vc1parse: set duration on output buffers
This has the nice side effect of avoiding hanging at EOS with truncated asf
clips.
