8e932639ba buffer: only warn if metadata is not writable when it should be, don't return as well
Make sure we execute the same code path in git versions and in releases,
so just warn when metadata isn't writable when we want it to be instead
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.

aa33db85cc gstbuffer: add additional checking for writability
Check for metadata writability when setting caps on buffer or when copying
metadata flags. Only enable these extra assertions in git versions.
This should help us find bad elements.

2008-10-06  Andy Wingo  <wingo@pobox.com>

* 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.
