When operating in streaming mode, qtdemux posts BUFFERING messages on the bus
if the stream headers are behind the movie data, to notify the user that
something is happening while it reads the entire movie data into memory.

These BUFFERING messages can confuse applications like gst-launch or totem
(which might change pipeline state based on them), causing 'hangs'.

qtdemux shouldn't post BUFFERING messages for this purpose.

Attached patch changes qtdemux to post element messages called "progress"
instead that applications can catch separately if they want to.
