* redhat/quagga.spec.in: Pass --enable-gcc-rdynamic to configure
	  to get gcc to link with -rdynamic for better backtraces.
	  When the rpm is upgraded, the restart logic now works as follows:
	  1. stop watchquagga; 2. stop all routing daemons; 3. restart zebra
	  if it was running; 4. start all routing daemons that were running;
	  and 5. start watchquagga if it was running.
