07f51390ea Fix for the non-virtual implementation of btGeneric6DofConstraint (mainly for Cell SPU purposes):
Need to explicitly call testAngularLimitMotor(i);, because it cannot be called during 'getInfo1', because m_rbA and m_rbB is not available.

b409abac09 Deltas of linear and angular velocities applied to rigid bodies now are kept between simulation steps.

1f38568f14 Fixing serialization issues introduced in previous commits:
0 maps to 0 (for getUniquePointer)

9acb3d1805 Added some improvements on Bullet serialization:
Introduced generated unique id's, instead of the pointer address to avoid 64bit->32bit truncation issues
Use serializer->getUniquePointer instead of directly using a pointer

moved  ChunkUtils::getNextBlock to bFile::getNextBlock.
Moved 'TEST_BACKWARD_FORWARD_COMPATIBILITY' to bDNA.cpp. Enable the define for further testing of .bullet format
Removed duplicate definitions and use the one in LinearMath/btSerialization.h

621eddb769 make btHashMap data protected (not private) for easier serialization
move btTriangleInfoMap.h into its own header, into the BulletCollision/CollisionShapes folder
add btTriangleInfoMap pointer to btBvhTriangleMeshShape, so we don't need to use the 'userpointer' anymore
preparation for serialization of btTriangleInfoMap.

d4c3633405 Get rid of btSolverBody and use btRigidBody directly. btSolverBody didn't improve performance after all, due to random-access
Tweak the BenchmarkDemo a bit: 

1) disable deactivation in graphical mode
2) add some settings that increase performance in the BenchmarkDemo2 (1000 stack) from 35ms to 15ms on this quad core (at the cost of a bit of quality)

1cd52f3d11 Removed empty constructors for constraints, I don't recall why we added them (possibly SPU) but if we really need them we have to revert this.
Moved static fixed body into a static function 'getFixedBody' to avoid issues when embedding Bullet in C#/CLI managed code.

d58081ce37 Provide easier access to CFM and ERP (and Stop ERP/Stop CFM) for constraints in a similar way to Open Dynamics Engine
virtual	void	btTypedConstraint::setParam(int num, btScalar value, int axis = -1) = 0;
virtual	btScalar btTypedConstraint::getParam(int num, int axis = -1) const = 0;
	
Parameter can be BT_CONSTRAINT_ERP,BT_CONSTRAINT_STOP_ERP,BT_CONSTRAINT_CFM,BT_CONSTRAINT_STOP_CFM
Axis is 0 .. 5, first 3 for linear degrees of freedom, last 3 for angular. If no axis is specified it will take the 'default' degree of freedom. For a btHingeConstraint this would be the hinge axis (5)
