gst/gstbuffer.c: Implement poisoning for GstBuffer if --enable-poisoning is specified.

Original commit message from CVS:
* gst/gstbuffer.c: (gst_buffer_finalize):
Implement poisoning for GstBuffer if --enable-poisoning is specified.
When finalizing a buffer the complete struct is filled with 0xff,
thus making a use of the buffer after the final unref impossible.

        Use fail_unless_equals_int(a, b) instead of
        fail_unless_equals (a == b) to get better output on failures.
