Added btAxisSweep3::resetPool, to avoid non-determinism due to unsorted linked-list, thanks to Ole K., See http://code.google.com/p/bullet/issues/detail?id=126

Fixed recently introduced issue: can't re-use stack as member variable (to reduce memory allocs) in btDbvt, due to recursion.
remove btGjkEpa.* from Makefile.am, Makefile and CMakeLists.txt
avoid division-by-zero in ODE boxbox contact reduction
