d85b800702 Convert DOS (CRLF) source files to Unix (LF) line endings
Excluded `examples/pybullet/gym/pybullet_data/` which has many (3000+)
CRLF data files (obj, mtl, urdf), and `docs/pybullet_quickstart_guide`
which has generated .js and .htm files with CRLF line endings too.

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.

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

Erwin Coumans
b5495e789d Change constraint solver threshold-based termination condition on residual of velocity threshold, not on residual of impulse threshold.
This avoids issues with systems with large mass ratios.

Test: add this to BasicDemo/BasicExample.cpp in initPhysics

	m_dynamicsWorld->getSolverInfo().m_numIterations = 1000;
	m_dynamicsWorld->getSolverInfo().m_leastSquaresResidualThreshold = 1e-4;
