The ASF specification of Metadata Objects' stream number is as follows:
"Specifies whether the entry applies to a specific digital media stream
or whether it applies to the whole file. A value of 0 in this field
indicates that it applies to the whole file; otherwise, the entry
applies only to the indicated stream number and must be between 1 and
127."
Yet the asf_o demuxer (the one originating from Libav) has always
treated such metadata as if it applied to a stream even though no stream
with a stream number may exist in a valid ASF file. This is fixed in
this commit; it affected e.g. the file
wma_with_metadata_library_object_tag_trimmed.wma from the FATE suite.

The other ASF demuxer btw applies all per-stream metadata to the whole
file.
