8375dc1dd1 asfdec: handle the case when the stream index has an invalid value better
The demuxer returned INVALIDDATA and failed to demux the remaining data
when an invalid stream index was read, now it just skips the asf packet
for the stream with an invalid stream index and continues demuxing.

ce70f28a17 avpacket: Replace av_free_packet with av_packet_unref
`av_packet_unref` matches the AVFrame ref-counted API and can be used as
a drop in replacement.

Deprecate `av_free_packet`.

b08569a239 lavf: Replace the ASF demuxer
The old one is the result of the reverse engineering and guesswork.
The new one has been written following the now-available specification.

This work is part of Outreach Program for Women Summer 2014 activities
for the Libav project.

The fate references had to be changed because the old demuxer truncates
the last frame in some cases, the new one handles it properly.
The seek-test reference is changed because seeking works differently
in the new demuxer. When seeking, the packet is not read from the stream
directly, but it is rather constructed by the demuxer. That is why
position is -1 now in the reference.

Similarly to what has been done for MOV, display XMP metadata only when

which are not strictly related to the video file, such as history of
edits and saves from the project file.
