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.

0af3b65880 asf: do not export XMP metadata by default 
Similarly to what has been done for MOV, display XMP metadata only when
users explicitly require it.

The Extensible Metadata Platform tag can contain various kind of data
which are not strictly related to the video file, such as history of
edits and saves from the project file.

0ebb523f07 asfdec: check ff_get_guid() return values during seeking

cc41167aed asfdec: Check the return value of asf_read_stream_properties 
This makes sure errors in setting stream parameters are passed
on to the caller. This avoids successfully opening files while
some parameters aren't filled in properly.

bb6d5411e1 asf: don't seek back on EOF. 
Seeking back on EOF will reset the EOF flag, causing us to re-enter
the loop to find the next marker in the ASF file, thus potentially
causing an infinite loop.
