Upgrade to latest Bullet trunk, that is in sync with Blender/extern/bullet2. (except for one define 'WIN32_AVOID_SSE_WHEN_EMBEDDED_INSIDE_BLENDER')

In case someone reads those SVN logs: you can enable some extra broadphase SSE optimizations by replacing WIN32_AVOID_SSE_WHEN_EMBEDDED_INSIDE_BLENDER by WIN32 in extern/bullet2/src/BulletCollision/BroadphaseCollision/btDbvt.h

Thanks to Benoit Bolsee for the upstream patch/contribution.
Removed some obsolete files, they were just intended for comparison/testing.
