39a4e8dcd9 Implement faster array versions of PyBullet: getJointStatesMultiDof, getLinkStates, setJointMotorControlMultiDofArray, resetJointStatesMultiDof,
Implement StablePD in C++ through setJointMotorControlMultiDofArray method for pybullet_envs.deep_mimic, see testHumanoid.py and examples/pybullet/examples/humanoidMotionCapture.py
Minor fix in ChromeTraceUtil in case startTime>endTime (why would it happen?)

ed4515ae17 for the GraphicsServer, expose a sync transform interval: only synchronize the transform once the stepSimulation exceeds this time interval.
(for example, run the simulation at 1kHz but sync the graphics transforms to remove graphics server at 30Hz)

c3b7f39aaf expose shadowMapResolution (texture resolution) and shadowMapWorldSize (size in meters in world space)
expose pybullet.ConfigureOpenGLVisualizerRequest(lightPosition=[x,y,z], shadowMapWorldSize=10.5, shadowMapResolution=16384)
See examples/pybullet/examples/configureDebugVisualizer.py for an example.
This reimplements https://github.com/bulletphysics/bullet3/pull/2295 but without creating a new command/status and explicitly referring to the debug visualizer
(since the 'getCameraImage' also has a lightPosition)

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.

85ee4c2934 allow batch creation of objects through PyBullet.createMultiBody, see createMultiBodyBatch.py example.
expose minGraphicsUpdateTimeMs through PyBullet.connect(p.GUI, options="minGraphicsUpdateTimeMs=32000"), by default OpenGL rendering runs at 4000microseconds intervals.
allow a maximum of 128k objects
fix meshScale for PyBullet.createCollisionShape for custom mesh
expose Pybullet.setPhysicsEngineParameter(minimumSolverIslandSize=...), larger minimum batches group solver constraints together in the same island, to reduce calling overhead (even if they are not related)

bf9efffa4b Increase mesh allocation for vertices/indices in PyBullet.createCollisionShape
See createMesh.py for an example.

The data has to fit in shared memory, hence the limit on Mac is lower than Windows and Linux:

#ifdef __APPLE__
#define B3_MAX_NUM_VERTICES 8192
#define B3_MAX_NUM_INDICES 32768
#else
#define B3_MAX_NUM_VERTICES 131072
#define B3_MAX_NUM_INDICES 524288
