demux: take chapter/attachment name strings without 0-termination

Change the demuxer_add_attachment() and demuxer_add_chapter()
functions to take a length argument for various name strings, so those
strings do not need to be 0-terminated. This will make it easier to
directly pass demuxed data without first making a copy just to add
0-termination. Also allocate the struct demuxer data structures for
attachments and chapters with talloc.
