added a cellDmaLargeGetReadOnly/cellDmaGetReadOnly, which avoid memcpy on non-SPU platforms.
...
enabled it for triangle mesh aabb DMA transfers. Todo: check if it is worth also modifying other parts of the code to avoid the memcpy into the 256kb Task memory.

- use mfc directly, instead of cellDmaSmallGet (allow sizes under 32 bytes, instead of 16)
...
- align btBroadphaseProxy to 16 bytes

BulletMultiThreaded needs to refreshContactPoint for contact manifold (this has been moved to the collision detector, instead of constraint solver)
...
BulletMultiThreaded support function for box shouldn't compensate for the collision margin anymore

multi-threading improvements: optionally use software caching (IBM/PS3), move some code from cpp to header to inline.

Added better support for btUniformScalingShape, by moving some data that is not shared from btConvexShape to btConvexInternalShape. This reduces the sizeof btUniformScalingShape to 16 bytes (from 64).
...
This is good when having lots of re-used shapes with different sizes.
Convex shapes will need to derive from btConvexInternalShape (which is a subclass of btConvexShape). We could have renamed btConvexShape to 'btConvexShapeInterface' (can still do that later)

SpuLibspe2Support is on the todo list, so it can run on Cell Blade & PS3 Linux.
