The attached patch adds event support to bytestream.  Here's how it
works:  When bytestream encounters an event, the event is saved and
it returns NULL.  Then you must call a new API to retrieve the event
and handle it:

void
gst_bytestream_get_status (GstByteStream *bs,
guint32 *avail_out,
GstEvent **event_out);

Whatever is necessary to handle the event is left up to the plugin.
Once the event is retrieved then the bytestream continues as usual.
