tests/instantiate/: Add test to test speed of caps copy and free.
Original commit message from CVS: 2005-03-31 Andy Wingo <wingo@pobox.com> * tests/instantiate/Makefile.am: * tests/instantiate/caps.c: Add test to test speed of caps copy and free. * tests/memchunk/gmemchunktest.c (main): Use alloc only on the GMemChunk to be fair. * gst/gsttrashstack.h: Remove warning about using the fallback trash stack implementation, it's still faster than malloc.
