PyBullet: try to address activation/deactivation issue with fixed base multibody with links.
Allow to compile pybullet using btDiscreteDynamicsWorld (no multibodies and no deformables), this allows to create Jacobian and Mass matrix (and A=J*M-1*J_transpose) with MLCP solvers Add examples/pybullet/gym/pybullet_utils/readwriteurdf.py, this allows to read a URDF and write the URDF with more reasonable inertia tensors (based on mass and collision volumes)
no btMultiBodyLink.cpp
fix premake build for linux, thanks to @consultit See also issue #1538
