Subject: BulletSim: Fix crash when linking large physical linksets. Properly
 remove and restore linkage constraints when upgrading     a prim's mesh to a
 hull. Lots more debug logging. Definitions and use of Bullet structure
 dumping. Centralize detail logging so a Flush() can be added for debugging.
