try to fix travis, update inertia for Laikago, reset camera at the right time (#3021) 
* laikago_toes_zup.urdf: fill in inertia values, computed as PyBullet does internally (from mass and collision volumes)

* reset camera in the rendering thread to avoid artifacts

* reset camera in the rendering thread to avoid artifacts

1e8f39b492 improve premake4 build in case X11 headers are missing 
improve video_sync_mp4.py example
allow to create a heightfield from file or programmatically in C++ robotics api. Example:

{
		b3RobotSimulatorCreateCollisionShapeArgs shapeArgs;
		shapeArgs.m_shapeType = GEOM_HEIGHTFIELD;
		bool useFile = true;
		if (useFile)
		{
			shapeArgs.m_fileName = "D:/dev/bullet3/data/heightmaps/gimp_overlay_out.png";
			shapeArgs.m_meshScale.setValue(.05, .05, 1);
		}
		else
		{
			shapeArgs.m_numHeightfieldColumns = 256;
			shapeArgs.m_numHeightfieldRows = 256;
			shapeArgs.m_meshScale.setValue(.05, .05, 1);
			shapeArgs.m_heightfieldData.resize(shapeArgs.m_numHeightfieldRows * shapeArgs.m_numHeightfieldColumns);
			double heightPerturbationRange = 0.05;
			for (int j = 0; j<int(shapeArgs.m_numHeightfieldColumns / 2); j++)
			{
				for (int i = 0; i < (int(shapeArgs.m_numHeightfieldRows / 2)); i++)
				{
					double height = ((double)rand() / (RAND_MAX)) * heightPerturbationRange;
					shapeArgs.m_heightfieldData[2 * i + 2 * j * shapeArgs.m_numHeightfieldRows] = height;
					shapeArgs.m_heightfieldData[2 * i + 1 + 2 * j * shapeArgs.m_numHeightfieldRows] = height;
					shapeArgs.m_heightfieldData[2 * i + (2 * j + 1) * shapeArgs.m_numHeightfieldRows] = height;
					shapeArgs.m_heightfieldData[2 * i + 1 + (2 * j + 1) * shapeArgs.m_numHeightfieldRows] = height;
				}
			}
		}
		int shape = sim->createCollisionShape(shapeArgs.m_shapeType, shapeArgs);
		b3RobotSimulatorCreateMultiBodyArgs bodyArgs;
		bodyArgs.m_baseCollisionShapeIndex = shape;
		int groundId = sim->createMultiBody(bodyArgs);
		int texId = sim->loadTexture(shapeArgs.m_fileName);
		b3RobotSimulatorChangeVisualShapeArgs args;
		args.m_objectUniqueId = groundId;
		args.m_linkIndex = -1;
		args.m_textureUniqueId = texId;
		sim->changeVisualShape(args);

c517c434e6 pybullet allow to enable/change joint limits: 
pybullet.changeDynamicsInfo(objectUniqueId, linkIndex, jointLowerLimit=..., jointUpperLimit=...) # jointLowerLimit <= jointUpperLimit

and joint limit max force:
pybullet.changeDynamicsInfo(objectUniqueId, linkIndex, jointLimitForce=...)

For example:
p.changeDynamics(sphereUid,linkIndex, jointLowerLimit=1, jointUpperLimit=3, jointLimitForce=10.5)

add b3ChangeDynamicsInfoSetJointLimit/b3ChangeDynamicsInfoSetJointLimitForce
add getConstraintType for btMultiBodyConstraint
