gst/id3demux/: Someone should kick my butt. Remove ID3v1 tags from the end of the file.

Browse source 
Original commit message from CVS:

* gst/id3demux/gstid3demux.c: (gst_id3demux_chain),
(gst_id3demux_read_id3v1), (gst_id3demux_sink_activate),
(gst_id3demux_send_tag_event):
* gst/id3demux/id3tags.c: (id3demux_read_id3v1_tag):
Someone should kick my butt. Remove ID3v1 tags from the end of the
file.

Improve error messages. Send the TAG message as soon as we complete
typefinding, instead of waiting until we send the first buffer.
Downstream tag event is still sent before the first buffer.
