50dca7cf0e Destroy semaphore after join
I can't quite work out the logic behind this fix though I get a consistent hang on the worker threads (both my worker threads get stuck on sem_wait() - Line 181) when the semaphore is destroyed before the thread is joined, and the application never exits.

This change resolves this.

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.

it can be disabled by setting the flag cb.m_flags |= btTriangleRaycastCallback::kF_DisableHeightfieldAccelerator;
acceleration is disabled for z axis up.
