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

c59afb88c4 Notify plugins on certain events (e.g. body added).
This also adds a periodic tick function to plugins, giving them periodically control over the simulation thread, even when the simulation is paused.

9c7aa3a863 Changes UserData to use global identifiers and makes linkIndex optional.
This removes the need to specify the body id/link index when retrieving a user data entry.
Additionally, user data can now optionally be set to visual shapes as well.

The following public pybullet APIs have changed (backwards incompatible)
addUserData and getUserDataId
  Makes linkIndex parameter optional (default value is -1)
  Adds optional visualShapeIndex parameter (default value is -1)

getUserData and removeUserData
  Removes required parameters bodyUniqueId and linkIndex

getNumUserData
  Removes required bodyUniqueId parameter

getUserDataInfo
  Removes required linkIndex parameter
  Changes returned tuple from (userDataId, key) to (userDataId, key, bodyUniqueId, linkIndex, visualShapeIndex)

7924d51665 PyBullet: deal with backward compatibility of b3RaycastBatchAddRay:
use b3RaycastBatchAddRays API to enable MAX_RAY_INTERSECTION_BATCH_SIZE_STREAMING num rays.
Old API (b3RaycastBatchAddRay) sticks to 256 rays, MAX_RAY_INTERSECTION_BATCH_SIZE.

04d03d10be Fix memory leak due to batchRayCast never deleting the btTaskScheduler.
(and issue with TaskScheduler/btTaskScheduler.cpp, add JobQueue::exit, call it first, since it uses the m_threadSupport which was deleted before the destrucor was called.
Use a hashmap to store user timers, to avoid allocating many identical strings.

f517b03534 Expose pushProfileTimer / pop ProfileTimer in PhysicsClient API to benchmark Python parts of PyBullet.
reduce 'm_cooldownTime' from 1000 microseconds to 100 microseconds (overhead in raycast is too large)
If needed, we can expose this cooldown time.
Replace malloc by btAlignedObjectArray (going through Bullet's memory allocator)

08409cae9f Adds multithreading support for batch ray casts.
To enable the feature, enable the BULLET2_MULTITHREADING option.

Increases the number of rays that can go in a batch request by storing
them in the shared memory stream instead of the shared memory command.
Adds the API b3RaycastBatchSetNumThreads to specify the number of
threads to use for the raycast batch, also adds the argument numThreads
to the pybullet function rayTestBatch.
Rays are distributed among the threads in a greedy fashion there's a shared
queue of work, once a thread finishes its task, it picks the next
available ray from the task. This works better than pre-distributing the
rays among threads, since there's a large variance in computation time per ray.

Some controversial changes:
- Added a pointer to PhysicsClient to the SharedMemoryCommand struct, this
was necessary to keep the C-API the same for b3RaycastBatchAddRay, while
adding the ray to the shared memory stream instead of the command
struct. I think this may be useful to simplify other APIs as well, that
take both a client handle and a command handle.
- Moved #define SHARED_MEMORY_MAX_STREAM_CHUNK_SIZE to
SharedMemoryPublic. This was necessary for the definition of
MAX_RAY_INTERSECTION_BATCH_SIZE.

bb72a91080 Clears the user data cache when syncUserData is called.
Adds unit test for the UserData functons.
Changes the char pointer in btHashString to std::string. There were
problems where the object owning the string memory would deallocate the
string, making the btHashString object invalid.
