This patch makes ffdec_* elements use gst_pad_alloc_buffer. I had to move the
call to negotiate. I don't like to have it splitted for audio and video but the
other solution (add a negotiated flag) was quite ugly.
With this patch a pipeline like decodebin ! xvimagesink goes down from 44% cpu
usage to 33% on my system.
