Fix btSoftBody issue, so it can interact with btCollisionObject and btGhostObject (and not just btRigidBody and btSoftBody)

Thank for the report mi076 http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=2823

remove legacy.c from libxml
removed #include <math.h> from btQuadWord.h , it should be centralized in btScalar.h (to allow easier replacement with fastmath.h etc)
