2.89
disable Extras BulletRobotics by default in cmake
Fix "seperate" typos
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
commit the ABA comparison test between the RBDL and Bullet, and use the option BULLET_BUILD_RBDL_COMPARE_TEST to control if build it. it is disabled by default.
bump up to Bullet version 2.89 and update serialization structures
update obj loader
Add Extras/BulletRobotics, will be installed as 'Extra Libs' using CMake Reduce size of command-logfile (used in PhysicsServer (Logging) and PhysicsServer (Log Replay)) Make Bullet3Common and BulletInverseDynamics part of core Bullet libraries (not optional)
add the 'extras' and Bullet 2 tests, to make it easier to create a new intermediate release
add premake4.lua build for BulletRobotics target, C++ API, similar to PyBullet. Use BulletRobotics target for App_HelloBulletRobotics (without GUI) and App_RobotSimulator
