A function that will be called from gst_buffer_list_foreach(). The buffer
field will point to a the reference of the buffer at idx.
When this function returns %TRUE, the next buffer will be
returned. When %FALSE is returned, gst_buffer_list_foreach() will return.
When buffer is set to %NULL, the item will be removed from the bufferlist.
When buffer has been made writable, the new buffer reference can be assigned
to buffer. This function is responsible for unreffing the old buffer when
removing or modifying.
