eb6663ed4b further work on shared memory API 
fix dependency of BulletDynamics to Bullet3Common (b3Printf)

26531f3fbc fix some warnings, disable gimpact by default in world importer, 
use DIRECTLY_UPDATE_VELOCITY_DURING_SOLVER_ITERATIONS by default for now,
until we find the issue with some failing test cases in btMultiBody
fix a crashing issue in MyMultiBodyCreator.cpp (uninitialized variable)
disable excessive debug printf in URDF2Bullet

6c9ce344ea fix shadowmap crash on some Intel GPUs, see https://github.com/bulletphysics/bullet3/issues/4 
remove targetdir from all libraries in premake, so it is much easier to create a separate folder for all binary+lib
transmit the serialized btMultiBody data back from server to client, after the server loads a URDF file. This includes base+link+joint names
tweak the serialization routines, so it is easier to skip pointers and to serialize directly to a shared memory buffer
also tweak the serialization code to allow to process data without 'DNA' schema data (assuming file-DNA = memory DNA)

f6f76901fd First draft of btMultiBody serialization, including optional names for base, link and joints (see ImportURDFDemo/ImportURDFSetup.cpp how this is done) 
Bump up version number to 2.84 because of new serialization data.

6e9eb13235 implement joint reaction forces for mobilizer motor/limit, by passing the constraint forces as 'external forces' and going through the Articulated Body Algorithm 
minor refactor for forwardKinematics, store the cached world transform in each btMultiBody::link

5d40d90bd0 add btMultiBodyConstraint::finalizeMultiDof API: if you add multi-body constraints to a multi-dof btMultiBody, before it has been finalized using the btMultiBody::finalizeMultiDof call, 
then you have to manually call the btMultiBodyConstraint::finalizeMultiDof for all multi-dof multi body constraints.
