fa0d993372 meta: implement transform function
Replace subbuffer and copy vmethods by a more generic transform function that
can then be parametrised by transform specific data. This should allow us to
implement make-writable and more future transform functions.

a55bc30f81 buffer: add pool to buffer structure
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.

58060d7528 meta: separate add and get methods
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.

8468dadc77 buffermeta: add beginnings of buffer 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.

of bailing out.

a184419ec5 buffer: allow configurable memory alignment. Fixes #596832
The alignment guaranteed by malloc is not always sufficient. E.g. vector
instructions or hardware subsystems want specifically aligned buffers. The
attached patch will use posix_memalign if available to allocate buffers.
The desired alignment can be set when running configure using the new
--with-buffer-alignment option.

67bd9529d0 buffer: remove subbuffer subclass
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.

* 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.

Original commit message from CVS:
* gst/gstbuffer.c: (gst_buffer_finalize):
Implement poisoning for GstBuffer if --enable-poisoning is specified.

thus making a use of the buffer after the final unref impossible.
