42ece54556 applied patch that allows to enable multithreading mode for CcdPhysicsDemo, 
Still requires manually adding BulletMultiThreaded library dependency (we won't enable it by default just yet)
Thanks SkewMatrix for the report/fix: http://code.google.com/p/bullet/issues/detail?id=222

e260bcd1b2 Added initial Smoothed Particle Hydrodynamics implementation (SPH), for CPU and CUDA. 
This software is contributed under the ZLib license by Rama Hoetzlein, http://www.rchoetzlein.com
We plan to integrate the SPH into the core Bullet library, including interaction with rigid bodies and soft bodies.

f3c3d2f156 + disable perturbation for btConvexPlaneCollisionAlgorithm, it introduces artifacts (additional points cause spheres/cylinders and other curved objects to move) 
+ applied patch to mix double/single precision meshes independent from double/single precision Bullet build
Thanks to Ole for the patch, http://code.google.com/p/bullet/issues/detail?id=213

700db838b1 Add 1D and 2D support for Bullet: using rigidbody->angularFactor(const btVector3& factor) and body->setLinearFactor(const btVector3& linearFactor); 
For example, to only allow linear motion in the X-Z plane, and only rotation around Y axis use:
	body->setLinearFactor(btVector3(1,0,1));
	body->setAngularFactor(btVector3(0,1,0));
Fix build issues with CodeBlocks, when generating projectfiles using CMake 2.6:
${OPENGL_glU_LIBRARY} should be ${OPENGL_glu_LIBRARY}
Fix build issue with CodeBlocks, comment out xmlfree in Extras/COLLADA_DOM/src/modules/LIBXMLPlugin/daeLIBXMLPlugin.cpp (will leak memory)

90f96aec27 Introduced btActionInterface. This makes it easier to extend user-defined actions, such as vehicles and characters. 
btRaycastVehicle and btKinematicCharacterController are derived from btActionInterface now.
Some cosmetic cleanup: changed sourceforce/sf.net url to bulletphysics.com.

459c22e7cb Synchronized changes of Bullet, from Blender. 
Added optional flag btSoftBody::appendAnchor(	int node,btRigidBody* body, bool disableCollisionBetweenLinkedBodies=false), to disable collision between soft body and rigid body, when pinned
Added btCollisionObject::setAnisotropicFriction, to scale friction in x,y,z direction.
Added btCollisionObject::setContactProcessingThreshold(float threshold), to avoid collision resolution of contact above a certain distance.
Avoid collisions between static objects (causes the CharacterDemo to assert, when a dynamic object hits character)

5be9f8f301 basic implementation of self-collision for btSoftBody with collision clusters: perform regular soft body versus soft body, but disable collision detection between clusters that are connected/share any node (vertex). 
currently self-collision is always enabled for soft bodies that use clusters collision detectoin. to disable, call 'softbody.m_clusterConnectivity.clear' after 'generateClusters(...) call.

210fe36106 Add backface culling and option to keep unflipped hit normal in case a ray hits a back-facing triangle. 
Usage: set RayResultCallback.m_flags to kF_FilterBackfaces, optionally combined with kF_KeepUnflippedNormal.
Thanks Andy O'Neil for the patch!

Remove the force_inline for some internal constraint solver methods, it makes re-use easier.
