gst_buffer_try_new_and_alloc() is replaced with gst_buffer_new_and_alloc(),
which now returns NULL when memory allocation fails.
* GstBufferList
The GstBufferList object is much simplified because most of the
functionality in the groups is now part of the GstMemory in buffers.
The object is reduced to encapsulating an array of buffers that you can send
with the regular gst_pad_push_list. The iterator is not needed anymore
because you can simply use gst_buffer_list_len() and gst_buffer_list_get()
to iterate the array.
For dealing with the groups, it's now needed to add the memory blocks to
GstBuffer and use the normal buffer API to get and merge the groups.
* GstEvent
* GstQuery
Boxed types derived from GstMiniObject.
