Original commit message from CVS:
* gst/gststructure.c: (gst_structure_id_empty_new_with_size),
(gst_structure_id_empty_new), (gst_structure_empty_new),
(gst_structure_copy):
add gst_structure_id_empty_new_with_size to allow preallocating
value array sizes. Use this in gst_structure_copy to get rid of
reallocs.
don't do quark=>string=>quark when copying structures
