Until now, vswitch.pic has been rebuilt whenever the schema changed. This is OK when the E-R diagram would really change, but many changes to the schema don't change the E-R diagram, and it surprises people when vswitch.pic changes in such a situation. This commit fixes the problem. Requested-by: Justin Pettit <jpettit@nicira.com>
