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.

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;

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)

b84eb8af74 Several fixes for the parallel raycasts
- Limits the maximum number of threads to 64, since btThreadSupportPosix
and btThreadsupportWin32 don't support more than 64 bits at this moment,
due to the use of UINT64 bitmasks. This could be fixed by using
std::bitset or some other alternative.
- Introduces a threadpool class, b3ThreadPool, which is a simple wrapper
around btThreadSupportInterface and uses this instead of the global task
scheduler for parallel raycasting. This is actually quite a bit faster
than the task scheduler (~10-15% in my tests for parallel raycasts),
since the advanced features (parallelFor) are not necessary for the
parallel raycasts.
- Puts 16*1024 of MAX_RAY_INTERSECTION_MAX_SIZE_STREAMING in
parentheses, since it otherwise causes problems with other operators
of equal precedence and introduces a smaller constant for Apple targets.
- Refactors the parallel raycasts code and adds some more profiling.

7924d51665 PyBullet: deal with backward compatibility of b3RaycastBatchAddRay:

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.

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.

Extract faces directly from btConvexHullComputer (in initializePolyhedralFeatures), instead of reconstructing them, thanks to Josh Klint in #1654

PyBullet: expose setPhysicsEngineParameter(enableSAT=0 or 1) to enable Separating Axis Test based collision detection for convex vs convex/box and convex versus concave triangles (in a triangle mesh).
