Patch by Dan Liew that removes our internal copy of STP, and makes the --with-stp option mandatory:
"1. At configure time the --with-stp= option is now mandatory.
 2. The HAVE_EXT_STP macro has been removed.
 3. The ENABLE_EXT_STP autoconf replacement variable has been removed and consequently the Makefile variable of the same name has been removed."
