04441a29cc Implement 'cone friction' for the rolling friction, to avoid curved trajectories for contact with rolling friction enabled.
(and separate spinning friction from rolling friction)

bdf9b10246 more work on pybullet_envs.deep_mimic.
allow btMultiBody to not wakeup (for some RL experiments)
move deep_mimic motion files to data/motions folder, so we can use the args files unmodified.

Better mass estimation while calculating spring forces in btGeneric6DofSpring2Constraint.
BT_6DOF_FLAGS_USE_INFINITE_ERROR flag has been removed as it's no longer needed.

Code-style consistency improvement: _clang-format applied

ab8f16961e Code-style consistency improvement:
Apply clang-format-all.sh using the _clang-format file through all the cpp/.h files.
make sure not to apply it to certain serialization structures, since some parser expects the * as part of the name, instead of type.
This commit contains no other changes aside from adding and applying clang-format-all.sh
