Add CMake install support for libbulletmath,libbulletcollision,libbulletdynamics,libbulletsoftbody,and toplevel include files
Options to enable/disable BUILD_DEMOS and BUILD_ETRAS
Fixed compile issue in BulletMultiThreaded
Fixed double-precision issues with btMatrix3x3::getEulerZYX
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
to build, go to Bullet/src/ibm_sdk and run make
then, go to Bullet/src/BulletMultiThreaded/ibm_sdk
make -f Makefile.original spu
make -f Makefile.original ppu
btQuantizedBvh has a version number, memory layout might be different now (due to aligned btVector3)
reorganized some data members of some classes, to reduce memory footprint

Fix btConvexTriangleMeshShape::calculatePrincipalAxisTransform
Both thanks to Ole.
Use our own union to extract a scalar value from an SSE intrinsic (instead of relying on MSVC-only m128_u32

Plan is to convert COLLADA XML into IFF, for faster, more compact and easier to read and parse files.
Reading/writing code is a few hundred lines of code, instead of COLLADA-DOM and libxml combo.
So it would be suitable as a run-time format for platforms ranging from iPhone to PlayStation 3.
Relevant physics data (and perhaps other data) will be converted from COLLADA -> IFF.
We could call the resulting files COLLADA binary IFF -> CLIFF.
BulletMultiThreaded/NarrowPhaseCollision makes use of this boxBoxDistance.
Cache some values in src/BulletMultiThreaded/SpuContactManifoldCollisionAlgorithm.cpp, to avoid DMA transfers
2) Added btConvexSeparatingDistanceUtil: this allows caching of separating distance/vector as early-out to avoid convex-convex collision detection.
btConvexSeparatingDistanceUtil is used in src/BulletCollision/CollisionDispatch/btConvexConvexAlgorithm.cpp and can be controlled by btDispatcherInfo.m_useConvexConservativeDistanceUtil/m_convexConservativeDistanceThreshold
3) Use BulletMultiThreaded/vectormath/scalar/cpp/vectormath/scalar/cpp/vectormath_aos.h as fallback for non-PlayStation 3 Cell SPU/PPU platforms (used by boxBoxDistance).
Note there are other implementations in Extras/vectormath folder, that are potentially faster for IBM Cell SDK 3.0 SPU (libspe2)
