Keep a pointer to the bufferpool. Release the buffer to the pool when
finalizing. Make sure the pool sets itself as the pool member of buffers that it
sends out.
Make separate api for getting and adding metadata. This allows us to pass extra
parameters to the init functions when creating metadata, which is needed for
specific API implementations.
Add beginnings of memory metadata.
Add first implementation of arbitrary buffer metadata. We use a simple linked
linked of slice allocated metadata chunks. Future implementations could use
something more performant.
Add get, remove, iterate methods to handle the metadata.
Add an owner private field where the owner of a buffer can store some extra
information. We can use this to implement most of the subclassing that happens
now. Later this will be removed and replaced by arbitrary buffer metadata.
This was required to add a new MEDIA4 buffer flag for indicating
progressive/mixed telecine video buffers. There is no space for
additional flags in GstBuffer, so steal one from GstMiniObject.

Make code including GStreamer headers compile with -Wcast-qual by
maintaining const-ness when casting. Also fix function signature of
gst_byte_writer_set_pos(): the byte writer should not be marked as
const.

Move the parent buffer pointer into the GstBuffer struct so that we can
remove the subbuffer class and type. This is interesting because it allows us to
more naturally implement methods to get the real type and parent
of a subbuffer (See #545501).
It should also be slightly faster because there is no extra object hierarchy to
initialize and free.
unref and copy functions are sometimes used as function
pointers for example in the case of g_hash_table_new_full
as a GDestroyNotify function.
Currently GstBuffer, GstEvent, GstMessage and GstQuery
define their respective unref and copy functions as
macros, making use of gst_mini_object_unref/copy.
This approach works very well for most cases, except
for some automatically generated bindings (currently Vala),
where the memory management semantics are defined
declaratively.
The possible solutions would be to either convert all
the macros into static inline function, or change the
signature of gst_mini_object_unref to take a void*
instead of a GstMiniObject*.
Fixes bug #572480.

* gst/gstbuffer.h (GST_BUFFER_FREE_FUNC): New API, a free function
that will be called on the malloc_data to free it. Basically a way
to avoid subclassing when all you need is a different free
function, i.e. free() instead of g_free().
* gst/gstbuffer.c (gst_buffer_finalize): Free malloc_data via
calling the free function.
(gst_buffer_init): Initialize the free function to g_free.

Make the default acceptcaps behaviour be to check the requested
caps against the gst_pad_get_caps output.
Ensure that gst_pad_accept_caps is used to check caps when a pad
doesn't have a setcaps function, so that pads automatically refuse
caps that they don't allow in their pad template. (Fixes#332986)
When a buffer with attached caps is pushed, ensure that the source
pad receives those caps even if the element didn't call
gst_pad_set_caps first.
